Tokico is one of the highest quality strut/shock replacement company available...From what i have read, the HP's (i.e. "blues"...) out last the illuminas (or most adjustable struts)....
Tokico, KYB, Bilstein, and Koni are pretty much the biggest suppliers of aftermarket struts...and all those companies make some OE equipment for some cars...
For adjustable struts I have heard that Koni's are the best...But that is other's opinions...We don't have that option so it really doesn't matter...Bilstein is famous for making sporty struts with nearly stock feel, and the HP's are more on the stiff side...
The only one of these companies that I have heard multiple complaints about it is KYB's non adjustable shocks (G-2's I think...)...Most say they are no better for stiffer spring rates than any stock struts, and don't last any longer...I have heard good things about KYB AGX adjustable setups though...
All of these companies have been around for a very long time (especially the european makes)...and they all offer very high quality parts...The Tokico's are very good, maybe not the absolute best overall, but by far the greatest option we have now (which is pretty much themselves or stock struts or E-spec KYB non adjustables)...If Bilstein made direct replacements for Proteges, there could be a debate on that...but with my experience in Bilstein's they were always on the softer side for my tastes...
