Both of them work. Only one of them fills up.
A shared cloud album is the obvious first idea, and there is nothing wrong with the instinct. You already have the account, it costs nothing extra, and you can make one in the time it takes to park the car. Then you send the link to the guest list, and the album collects photos from the people who happen to live in the same ecosystem you do and who found the right button. Everyone else looks at an invitation they cannot accept, and puts the phone back in a pocket.
That is not a design problem or a quality problem. It is an account problem, and it is the whole argument. If you want the setup side instead, the wedding photo QR guide covers it end to end.
The invitation not everyone can open
Picture the tables at your reception. Your college roommate is on an Android. Your father-in-law has an iPhone and has never knowingly signed in to anything on it. Your cousin has a Google account she uses for work and will not put wedding photos in. Your friend from abroad signed out of iCloud two phones ago to free up space and has no idea what the password was.
Every one of them takes photos at your wedding. None of them is going to create an account at the bar to give them to you. The invitation to a shared album is not really an invitation to share photos. It is an invitation to log in, and then share photos.
The account wall, plainly
Here is the part that rarely makes it into the comparison posts.
Google Photos. A guest can often view a shared album from a link, but adding photos to one generally means signing in with a Google account. What quality those photos land at depends on the uploader's own backup setting, not on yours, so two guests can add the same moment and hand you two different files.
iCloud Shared Albums. Contributors need an Apple ID, which rules out a slice of the room before anyone has taken a picture. And Apple's own documentation is clear that photos and videos in a shared album are stored as reduced-size copies, so what you end up holding is not what the phone shot.
Neither of those is a scandal. Both products are doing exactly what they were designed for, which is letting a family that already shares an ecosystem pass pictures around. A wedding is the opposite of a family that already shares an ecosystem.
The quality question, briefly
The reduced-size copy is the second cost, and it is the one people notice a year later when they try to print something. A shared album that stores contributions as smaller copies has quietly decided, on your behalf, how large your wedding photos are allowed to be. If you want the full walk through what each path does to a file, the compression chain is its own piece. For here, it is enough to say: the account wall decides how many photos you get, and the storage policy decides how good they are.
What each one gives you
Three of those rows come out even, which is the point. The differences are not where people assume they are, and a comparison that pretended a shared album was bad at everything would be worth nothing to you.
One row deserves a footnote in the other direction. A Partyreel event asks nothing of a guest's ecosystem, but by default it does ask for a one-tap email code, so every upload has a name behind it. That is not an account in the sense the other two mean: no app, no password, no profile to maintain. And if your event is the kind where even that is friction, the host switches Require accounts to upload off and guests upload with nothing at all. What guests see either way is spelled out in how guests join and upload.
What a QR event album does instead
The mechanism is boring, which is why it works. One code, printed on the table cards. A guest points the camera at it, the browser opens, and they are uploading in the next tap. Nothing is installed, so there is no ecosystem to belong to and no version of the room that gets left out. That is the entire pitch of the guest side.
Underneath, three things follow from that. The originals are kept as they were shot, so what you download in a year is the file the phone made. You get a review queue, so nothing appears in the album until you say it does, which no shared album offers. And when it is over, the album can end as a highlight reel rather than as a folder nobody reopens.
Which one is right for you
Be honest about the room. If your event is eight relatives who all have iPhones and are already in a thread together, a shared album is fine, and you should not pay for anything. It is simple, it is free, and the account wall costs you nobody.
If your guest list crosses phones, generations, and accounts, that same wall is a filter on how much of your day you ever get to see, and it filters hardest on exactly the guests whose angle you do not otherwise have. Weddings are the least ecosystem-uniform gathering most people ever throw. That is the case, in one line: a shared album is a place to put photos, and an event album is a way to collect them.
Still deciding between all the options rather than these two? The full ranking puts chats, AirDrop and file requests in the same table. Otherwise, start with the wedding QR guide and have the code ready before the invitations go out.
