Like many things in life, there are pluses and there are minuses. Nothing you choose will be perfect for everything you do. You will always have to come up with workarounds for certain tasks, but if you pick something that has a higher percentage of work-ability with your habits, then you will have found the best option for you. How do you do that? Well, grab a sheet of paper, go in the shop, and start writing down everything you do on your bench. Then, be honest with yourself. What vise, or whatever, will work the best for you in these situations? There's your answer. Wasn't that easy? No? OK. well, obviously experience with different vises helps, so here are some of mine and how I figured out the leg vise was better for me.
However, because of how good this vise does with dovetail work, I did install it on the back side of my 6 foot bench (pictured above).
The killers for me are these. One, yes they are simple to install, but if you want it to be flush to the bench front, you have some extra work to do. This is the biggest killer for me. I like the flush rear jaw, yes it can be done with almost every quick release vise, but I also don't want to cut into the front of my bench either. Second, again like the twin screw, it doesn't have a deep throat. This isn't a big deal on longer benches but is an issue with short 6 foot benches like mine. Third, when clamping boards vertically you just don't get that good of a grip because the guide bars make you clamp on the extreme ends. Yes, you can add wider jaws, but that just increases racking and that's not fun either. I do use a quick release daily at work and it works great for what I do there, but not for what I do at home.
The thing to take from this is not so much why I made my choice, but how you should make yours. Think about what operations you do most often, how much room you have in the shop, what is the most important feature for you, and then install the vise and work with it. Only you know what will work best for you. Don't let me, or any magazine article, sway you one way or the other. You will always regret those decisions, trust me on that at least.
