Well, we're talking about my favorites steels. I like them all precisely for some of the differences that get debated so much. But, if you want my OPINION....
I have a lot of experience with SR101. In my experience, you get a lot of work out of sr101 before the need to resharpen. And then the edge is easily brought back. It almost seems as if it defies the laws of nature in that regard. It accepts stropping very well and can be made absolutely screaming sharp. Of course we all know that Guy produces scary sharp 3V as well.
Most of my 3V experience is from BRKT. Gunnys, liten brors, mini fox, kephart, etc. and the GSO 3.5. I got to use the 3.5 pretty hard last year, it wasn't all cleaning trout

In side by side use, cutting the same materials, I believe 3V will stay sharper longer than sr101. At least properly heat-treated 3V, as we are seeing testimony from those like Mr. Carothers that points to the need for proper heat-treat protocols with this steel. I really appreciated HaleStorms's side x side test of 3V vs S35VN, very good real world information :thumbup: I have had no bad experience with 3V yet, and my GSO 3.5 is very good. When 3V dulls, though, you're going to spend more time bringing it back than you will SR101. Some draw the conclusion that SR101 must be inferior in the edge-holding aspect strictly based on ease of resharpening. From my experience, SR101 is freakishly easy to sharpen. So much so that it should not be used as an edge-holding indicator. Cutting tests would be much more appropriate edge-holding indicators. For me, 3V wins in the edge-holding aspect, but 52100 is still very good, and remember, we are talking about GREAT steels here.
I think we sometimes get hung up on finding perceived strengths vs perceived weaknesses. Sometimes a quality in a steel is not better or worse, but just different. For example, how likely are you to need to resharpen in your outing? Not likely, you say, because you have a 3V blade and it holds a great edge. Everything dulls with enough use. Will I be out for a day trip or out overnight? Will I be hunting chukar out the back door for the weekend, or muledeer in the Owyhee mountains for two weeks? If you find yourself needing to sharpen 3V in the field, you will need the proper equipment to do it, probably diamond, it's going to take a bit of effort. Not such a big deal to field sharpen SR101. A perceived weakness can be turned on its head, depending on what YOUR outing is going to look like. I pack 3V a lot since most outings are by necessity shorter, and I can always resharpen at home/work after having enjoyed the great edge-holding of 3V for whatever tasks I needed accomplished that trip. Your circumstances may vary YCMV!
All that to say (Yes I know I've said it before) : If I could have the same blade, with the same grind, at the same price point, I will take 3V every time

Getting all that to line up is kind of like witnessing a solar eclipse, though, so SR101 still has a spot in the lineup. It's like going to the gun cabinet and selecting a weapon for varmint hunting or elk hunting, options are good! If you all don't lynch me, we can still debate stainless vs non, toughness, price point, etc. Just don't ask me to give up any 3V, INFI or SR101
