Almost identical, but not:
1. Pictures upload weird so you have to manually sort them into an album
Not actually true. All my events and albums and smart albums (and projects for that matter), Faces, Keywords and so on converted to Photos perfectly. I also still have (and use) my iPhoto library, since neither it nor the application were altered in any way.
2. You can make a smart album based on a keyword or a face
Faces are of course already sorted into albums automatically, but yes you can (easily!) make a new album based on a face, a keyword, or just about any other criteria you want. You simply haven't bothered to learn even the basics of the program, as evidenced by the picture below:
3. They got rid of photo stream and make you pay for no apparent reason
Nope.
4. Face makes you work a lot harder to tag a face
Not really, it's just moved to the "Faces" section. You select one of the suggested faces, and tag it same way you always have.
5. Faces doesn't allow you to select more than one face at a time
I'm unsure what you mean by this, but I can, in fact, select multiple faces in the Faces view by holding down the command key.
5. Batch edit date and time is gone so you have to change each photo by hand
(two number fives, btw) And again, no you are incorrect. Select all the photos you want to change, select "Adjust Date and Time," adjust the date and time and click okay. All photos selected will be adjusted (either the copy or the original as you indicate -- just like it worked in iPhoto!)
So now that we've shown every one of your complaints to be invalid, let me tell you about one you missed that is a **legitimate** complaint about Photos. Unlike iPhoto, it doesn't allow "round-tripping" to a third-party photo editor. However, it does (as of El Capitan) allow third-party plug-ins, which may negate this issue entirely over time. But for now, that's what is keeping me in iPhoto.
It's amazing how many "lost" features reappear if you take the time to learn the new program -- and very often in doing so, one starts to understand why things were changed in the first place! That Adjust Date and Time change makes perfect sense when you think about it for two seconds!
