Both are underwhelming in my opinion.
MCU version didn't make a huge impression, he died, and his death may not even be mentioned ever again. Leaving that out of Wanda's Civil War story was a HUGE mistake and it seems they just want everyone to forget the character even existed due to the popularity of the Fox version.
The Fox version is merely a gimmick though. The gimmick worked in the first film and got a lot of laughs, but like most gimmicks it grew stale by the next time it was used. His slow motion scene in Apocalypse didn't even make me crack a smile because it was just the same thing in a different setting, and it was forced and overlong. Also forced was the search for daddy storyline. It wasn't developed or important enough for anyone to care, and only included to give forced depth to a popular one dimensional character (as he was portrayed).
If I had to choose I'd choose the MCU version, just because he was merely fine, while the Fox version has gotten annoying to me. I accidentally voted for Fox in the poll though lol
