I have been a Warwick player for over 10 years - having owned a rock ass streamer, lx 5, stage 1 (both 4 & 5 string versions) and now the proud owner we of a stage 2 5 string + PNUT signature bass I can honestly say there is a huge difference in quality between them.
The ss2 and pnut are too notch on all fronts - both very different basses but incredible tones and playability. The LX range I owned was great with a lovely tone but still noticeably different.
If you look at the link in my signature to my playing, you will find several examples of each of the basses ive mentioned here, and my YouTube channel has even more.
I'd suggest find one you like the sound of first, then go and play a couple and see what you like.
