Quite true - and I love both my JP Metroline 4 and 5 !!I have always felt the fingerboard makes a bigger tonal difference than the body wood. Maple is the tightest and brightest, and rosewood is sweeter, fuller, and warmer. You can read more here: https://shrtm.nu/xr2g9jK
From my experience, the neck makes a big difference too. Directly comparing my two Warwick Stage-I with the same maple body, wenge fretboard, PJ PUs, and MEC preamp: the '89 has a wenge neck with 3 maple stringers (boomy dark), the '90 has a maple neck with 3 wenge stringers (bright and snappy). Completely different animals. Diversity brings the pleasure
Srsly, it's a matter of "different", not "better". Reverse does have more punch/growl on the BEA strings -- but also less "thump". And the DG strings sound like a J neck pup, not a P.
