I'll chime in. Here is what I experienced with each bar installation.
I firstly installed Yoshifab's tower to firewall braces. They provided the most bang for the buck in steering stability in turns. I then installed Yoshifab's bottom bars, which tie the engine cradle to an existing threaded hole in the frame. They greatly affected the way the car stopped - very controlled and straight with controlled nose dive. These were the biggest bangs for the buck. The front end felt like a part of the car rather than separately attached to the car.
I then installed a CravingBoost tower to tower brace which is no longer available. Why I chose this specific brace is its adjust-ability. Not a requirement but something that worked for me. This brace was less noticeable except under very hard cornering or uneven surfaces. It does provide the last word in front end integrity however, but if funds are a concern, I would submit you could do without that brace until funds are available. It is really discretionary but I am happy I installed mine for sure. There is also the visual when you pop the hood and see that bar. Heh, I admit it.
I had previously scored the flat steel IPD bottom brace with the cross bar but had not installed it. I decided to add it in anyway. What the heck. It installs to the rear bushing cup so a hole was drilled. Kinda hokey but I did it just to get the cross bar in the mix. In retrospect, I could have just gotten way with the IPD cross brace but Yoshi's bars are just so darned stout and they attach to the frame.
After all is said and done, what I will say is the front end is, well, stout, that's for sure. Along with the sway bars, springs and shocks, it handles quite well. Admittedly, I don't drive that hard but an anecdotal comment from the mizzuz sums it up nicely. When a garbage can dropped off a truck in front of me out at speed out on the interstate and I took emergency evasive measures, before she could come unglued we were around the hazzard as if it never happened. She said, "I guess I now know what those upgrades did to the car". Uh, yeah....
