I wouldn't say "several" mid-range spinning reels vs. one high end reel. It is more like two, MAYBE three mid-range reels vs. one higher priced reel... IMHO
But everyone's needs are different for the type of fishing they do, and the type of budget they have... Opinions will always differ and if they didn't, than life wouldn't be interesting .
As for Stradic FI and the PQ, you will get what you pay for... Shimano spinning reels are notorious for lasting lifetimes, and they are very dependable. The PQ will get you by in the short-term, but if you want long-term "bang for your buck", I would actually say that the Stradic will get you more of that.
