I find Gitlab UI quite a bit bloated and slow compared to Github. They have some amazing features but I can't get past how many (2-5 seconds) to load a page and sometimes upto 10 seconds (analytics). I hope that's being addressed in future. Usually, I spend at least 2 hours on Github in a given day - and probably access the website about 50 times a day or more. These UI issues add up tremendously.
