Two reasons:
Fanboy's gonna fanboy. Quality control. AMD has gotten a bad wrap over the release of NAVI with poorly optimized drivers and firmware.  While later releases have for the most part solved those early issues, the damage has already been done.  Couple that with some manufacturers not doing their due diligence in quality control leaving some cards with performance issues.  All things aside, if I didn't have a capable 1070 I'd be all over a 5700XT.

I would say IPC is more important than clockspeed, as Ryzen's IPC is far superior to 'Coffee' lake, which is why in artificial benchmarks similar core count ryzen CPUs match or beat higher clocked Intel parts. In fact, if Intel was on 10nm right now they would likely face a clockspeed degredation due to years of tuning the 14nm silicon, and it would truly be a war of IPC. Intel would still probably win, however, in games, due to Ryzen's CCX design adding latency in any game that uses potentially more than 1 core, as it assigns random cores in a CCD, not CCX. 

I bought a sapphire pulse 5700xt a month ago. For me it was a no brainer between that and the 2060 super for $400. 

I haven’t had a single issue with this card and those newer drivers. I did have a 5700 non xt the month before I got the new card and had nothing but issues with it. 
 
To each their own when it comes to hardware. I look at performance numbers and buy based off of that. Ray tracing I could care less about, I play shooters and care about framerate so I want power not special lighting effects. 

All of the 5600xt, 5700 and 5700xt are really good deals as they deliver very good performance for the price, I always recomend 5700xt cards or 5700 if you need just a 2 fan gpu. 
 
 
I have a vega 64 and no issues from ages with drivers. Just keep the system clean and make sure that no OC on any part is making issues, yes even XPM counts to something to look at.
