XF is the best by far. the case and bezel are miles ahead of ARF.
This is not true anymore, but was 100% true a few months ago.
The ARF V4 is on the NWBIG list for a reason (incl. V3 iirc, but could be wrong). Both are amazing, please don’t get me wrong. The XF/VSF has better CG’s and there is def a nice insert on it. But the HEV, SELs and bracelet def take away from it. Often not mentioned is how oddly noisy the clasp is. Not sure why, feels hollow almost, hard to explain, but next to the ARF the clasp is def different.
ARF has worse CG’s, but most don’t see it, and the insert on the V4 is amazing. ARF bracelet we all know is better, and as above so is the clasp. SEL fitment on the V4 is spot on, case shape measures to exactly the Gen in every measurement I’ve taken when comparing, which I am so sorry I do not have pix of.
I bought the latest ARF and XF solely to make a hybrid of the two, and once in hand, and after very careful consideration and staring at them together for a few weeks, I just couldn’t see the benefit. In person, the bezels are almost impossible to tell apart. In person, I could tell the watches apart by the SEL fitment and the clasps the most. Some pix for reference…. You can tell which is ARF V4 and which is XF/VSF, both are amazing. (Side note: the ARF winds smoother, tho both are A2824’s, and in these pix has a Gen grown)
