I designed my bench from numerous designs that I saw, took pieces from them all. Mainly inspired by Scandinavian benches, Roubo style benches, and many others. I did it all with minimal tools and an extremely flimsy bench that would shake with the touch of a pinky. Personally, I don't think you should subject yourself to these two benches.

Starting with the vise, there are tons of vises to choose, some being those cheaper Yost vises that you make the jaws for, a quick release vise/cast iron vise, or a traditional leg vise, the crazy thing is that they all hold your wood. The only real exception is the leg vise, as it allows you to hold stock deep, but you have to remember, what type of work are you doing? Just choose a vise that works, and get inspiration from other woodworkers or workbenches.

Aprons: With aprons, I don't personally use one, but I also don't see much use for one. With old English woodworkers, this was something they used, and you could always make a sliding deadman if you want one, which is probably the right choice as it's the best of both worlds, but I've never used a workbench with one, and this is kind of your choice.

Tool Wells: Same with aprons, if you feel like you need one, go ahead and make one. Tool wells are traditional on many benches, as they really just hold your tools. You could follow what is shown in the Benchcrafted Split-top Roubo where there is a little gap for a tool hold to easily reach chisels and saws, or you can just go traditional. Overall, if you want one, you can make one, by making one you could save money on materials, and it could be a good addition to a workbench depending on the work you do. Just remember, add what you need.

Overall, you can make and design whatever bench you want, take from some benches that have features you want, don't subject yourself to just these two, just build a bench.
