FFX was great for me and it is in my random top 3 FF games (FFVI/FFIX/FFX) can't really decide which one is my favourite depends on my mood.
FFX blew me away, the characters like Auron are my cup of tea, the music was outstanding and what people should not forget this was basically the first mayor JRPg with voice acting and sure we can lauch with the hahahaha part but it was a big deal for us.
I loved the new level up system, I personally disliked the simple 'level up to 99' mechanice some games had and I enjoyed the very big level system from FFX.
I remember how I almost was finished the game and then went to besaid and got attacked by the Dark Valefor Aeon and he killed my team...Went back to leveling and came back to defeat him, felt great and then found out he wasn't the only one...
I went so far that I bought it again for PS4 and have the platinum for all the FFX related games ^^'.
While FFX-2 wasn't that great the monster arena aspect was something that people really should not miss, people never knew that you coudl play with characters as lulu/Tidus in FFX-2 till I showed them =p.
