Can anybody in the world tell me why did y'all hate Joey & Rachel relationship. I mean they were so much better than Ross and Rachel

It was just awkward. They'd been shown as Friends for years at that point. Also, the actors found it awkward too - they've admitted it - and this showed in the performances.

I don't hate Joey and Rachel's relationship I just think that Ross and Rachel had a bigger connection. It's weird to see Rachel and Joey dating because they were best friends.

After like eight seasons of being just Friends they suddenly are in Liebe and it´s very awkward , it worked with Chandler and Monica but Joey and Rachel seemed Mehr like "lets pair them and see what happens"

Because ew, Ross and Rachel complete each other, opposites attract

I kinda thought they would be hot together too. Plus it was really sweet to see Joey finally in Love!! But I think because she and Ross had the baby and everything that why people really wanted her and Ross back together. He was kinda a jerk he loved her for ever then gave up way too easy! And FYI jealous guys alway wind up cheating themselves!!
