Google photos is excellent. I hated the demise of picasa, especially when the first incarnation of photos was terrible, and was tide to google plus with an anchor. But now it’s almost perfect, and the search is great. I have pictures dating back to 06, I backed picasa early.
Also i upload to Flickr, that to is excellent, but isn’t as simple as GPohotos. But great non the less. I was uploading their before picasa, by about a year. You just need to watch whenever you create a new album you change it from ‘public’, to ‘private’. ‘public’ is the default.
I use one drive and mega, as a photo dump. I have 365 but really don’t like it. I use it for spreadsheets, but will always just google docs over office, it’s just better imo, and Google drive is great. You can duplicate all your photos fron GPojotos to Drive if you wish, I don’t, but it’s there if you want.
