Who was the endgame Spike and Buffy o ángel and Buffy

Neither. Spike gets blown up in Sunnydale and Buffy goes on to live a normal life after Willow casts a spell to make all women able to stand up for themselves and be like Slayers. Buffy and ángel do not get back together either. ángel stays in LA fighting the evil there and Spike is ressurected and fights at ángeles side for the last season of Angel.

Well if tu follow the comics, Spike and Buffy is más likely to happen than Buffy and Angel, especially after Season 8.

well if tu follow the comics which is a continuation of the series spike and buffy are más the end game it just going to take awhile because spike has been through alot since he got his soul and buffy has since the hellmouth was gone thanks to spike.
