Welcome and Happy New Year.
Here is a few things to think about
Try and figure out where you want to end up (lift and tire size) before you buy anything. That way, you don't have to do things twice...or more...like me.
The most cost effective is the 2" BB. Better, but more expensive, would be a good 2" spring lift. Combined with some 31" tires will give it a nice look. It will also take you a lot of places with minimal accompanying modifications. Because......
Lifting a TJ more than 2" requires a bunch of other junk, and money....if you want it to be safe, drive right, and not compromise your offroad ability with a transfer case drop.
Installing a Budget Boost spacer lift re-uses the stock springs. Fine for me when I had one as my TJ only had 11K miles at the time. Nowadays, a lot of stock Jeep's springs are reaching the end of their life and starting to sag.
Installing a BB also requires complete removal of the stock springs to install the spacers. Since you've already gone through the trouble to remove them.....see where I'm going with this one?
My opinion, and you'll get others: For staying low, DPG Offroad has some nice OME lifts. Going taller and spending lots, Savvy/Currie and Metalcloak. Middle of the road budget lift, Zone.
Endless choices, hours of reading, and TONS of different opinions.
Have fun with your project.
