Oh speeds are great! Hundreds of Mbps. Depends on what you're after. Not sure if they go into the Gbps, but I feel like I remember some locations do. My internet is only 300Mbps so can't test higher. VPN speeds from a random local server are normally about 280Mbps. Not sure if that would be higher if my internet was faster.

I haven't had any connection drops, and you can choose the location. Their guides also explain which locations work for streaming services if you want to check out the catalog from other countries. And they have specific servers that have P2P enabled if you want to use bittorrent.

I haven't used Proton Drive for photos. It's worth noting Proton Drive is a relatively new offering. The lack of Linux client is also a show stopper for me, as I don't have a Windows computer to run it on. I'm keen to use it though when they get a client going.

The proton mail mobile app is fine, I use it and don't have complaints. But I don't like that I can't use a different app if I want to 😆. It also doesn't let you add other third party accounts into the app with IMAP so I have two apps while I transition.
