The LBP, JDI and Whirlwind IMP2-JT all use the the Jensen JT-DBE transformer, so the performance ought to be identical. It really comes down to which form factor you prefer. I've owned half a dozen that I built 20 years ago, also using the JT-DBE transformer, and they've always done the job for me. To eliminate any switches, I put in two XLRs instead. One has the ground connected, and the other has it lifted (with an RF bypass cap), so nothing can get changed inadvertently after I plug things in.
While the DIs mentioned above are first choice general purpose boxes, I think it's a good idea to have the option of an active box available when you had to interface a piezo pickup and I like the Radial Pro48 for that. The performance is the same or better than the J48, but it is smaller, the power LED stays on all the time, there are fewer switches to get put in the wrong position, and at about $100, it's quite affordable. It doesn't have the merge and polarity switches like the J48, but those are some of the switches I consider superfluous.
There are probably other active DIs you should consider, but except for the J48s, I don't have much experience with them.
