My group switched to 5e. We played it for a few months and have since moved on to other systems. It literally killed our desire to play D&D.

Why didn't we like it? Well, the combats were so incredibly omg boring. The martial classes went back to basically not getting any options (compared to 4e) and the casters once again dominate. After experiencing 4e and how classes were (relatively) equal in power, it felt like going back to Pun-Pun.

Granted, I'm biased. I really enjoyed 3.5 when it was out and absolutely loved 4e. 5e is the first edition that my group genuinely dislikes. A lot of people switched from 3.5 to 5e and loved it, but coming from a group that loved 4e? We can't stand 5e.

Now - I'm not saying that you shouldn't try it. You should try it. A lot of people really enjoy it -- my group just isn't one of them.
