Well, I don't see anything great about google services. some people might just like I see Microsoft services to be great. but I really roll my eyes when I see so much adquisitions and then "no more for Windows phones" at least Waze got an update some of these days, I don't use it myself but if someone uses it it should be good.
The only service I use from time to time it is YouTube. but I don't use it because I want it is becuase many videos from 3d products I like are uploaded there. of course whenever they upload to Vimeo, which is used alot by 3d artista and companies, I run there as fast as I can, it loads faster and to me it looks better while not buffering it like crazy.
But when I can I copy YouTube video address and just paste it into PotPlayer, so I don't touch google ads or anything and I don't have to deal with the way it plays.
But yeah, I stopped using gmail because I got many spam email, like 100 daily. and that was before Windows Phone was released, and everytime I see how things work on their services like google docs and stuff or gdrive... I really don't understand why people would choose them apart from "Microsoft sucks" some people I know uses.
I must admit I use google search sometimes when I am really desperate to find something, and bing doesn't find it or I want more answers to my question. but not often, just couple times a month. while I use Bing for most searches and stuff. and i am not from US so people can't say anything about "It is only good for US". it works great here, and I can change it to US bing whenever i need it. not like I die for 3 clicks I have to make.
