If you like rich, earthy flavors and robust tobacco, then the BPC is a good one to try. Personally, I have yet to have a good Monte 4. While it certainly has a very different flavor profile than the Bolis, I'd say the inconsistency has to do with instances of sticks with an almost complete blandness to them. This has been the case with the Monte 4 in the form of the Monte 4 as well as the Petit Tubos. The Sig II is much milder and a bit sweeter IMO without the rich tobacco flavor. I'd put up some Sig II if they weren't so pricey. As it is, the Juan Lopez, Boli, RA and RA petit coronas meet most of my needs. The PLPC is just so hard to find or so pricey that I can't really consider it a candidate for smoking rotation. Oh, and if you like the PC size, it might be worth your while to try the tubos (Hdm Coronations, Punch Coronations, RyJ Romeo No.2 Deluxe) for a change.
