Both are solid options. Bad examples of each exist, quality is quality, whatever you get, get the best.
I like sliders.b/c either way the Chainstay length changes (EBB vs sliders), but with sliders the cranks do not move relative to the saddle....and the tire clearance thing.
Your choice...I do not think there is clear winner between the two.
I just sold off my 10th Anniversary Diesel with a pinch bolt EBB, and replaced it with another SS frame with an EBB. Personally, I just prefer the clean look of the EBB to the somewhat complicated sliders. FWIW I had the bike for 4 years and never had a single issue with the EBB.
