2 things I'm not a fan of about blower styles
1) they are louder than Arial designs.
2) require more maintenance than Arial designs, there's limited airflow access in the fin channels, they must be kept dirt free or temps go nuts especially on the vram/VRM's section of the pcb which is the section closest to the back of the case and has no temp sensor.
2 things I do like about blowers.
1) heat? What heat? Gpu heat is almost negligible with respect to case temps and airflow.
2) in smaller cases, the blower helps act as a case airflow exhaust and with many mini towers that's important as the 80/92mm fan is often the only exhaust available, making Arial designs another bad decision.
Blowers have pros and cons, arials have pros and cons, so the choice becomes as much situational as it is personal.
The difference between a FTW and FE? About 10fps or so, on the top end, where it's basically useless as it's usually beyond the scope of the monitors refresh. The only time the OC models are any benefit is when the fps is Under the refresh value. So a 1060-6 FTW on a 1440p monitor would be better than an FE, but on a normal 1080p/60Hz monitor, it's a waste of cash. (just using the FTW as example).
As is, the FE has well documented history, any issues it has are not really an issue anymore, the Evga though (from everything I've seen) has sometimes had cooling issues, the pot-luck/you might get a funky card, kind.
If that extra few fps is important and you can live with the gpu heat lottery that seems to plague Evga currently, go for the SC. If it's not that important, the FE is a solid choice.
