Ok, I'll give you what I think. First off, I'm on Xbox One, so all my impressions of the hardware are for Xbox One. I will give you my thoughts by way of comparisons. Jag vs. Strat is simple. Jag feels better and more durable. The Strat's auto calibration didn't work very well and had to be done many times. Jag took one try and it was great calibration. Jag is just a slight bit longer in the neck and head. All the non-neck buttons are in a slightly different spot on Jag, so that takes a minute to get used to. I really enjoyed the 12 or so hours I put into Jaguars play. It has been one of the better guitars I've ever touched. RB4 Strat, to me always seemed a bit lesser than the quality of RB2 Strats. Jag's fold-able neck is cool. Truthfully, I have not folded it since I got it, but people who travel with their axe may find it awesome. I would buy a Jag before a Strat, personally. Jag, just to me, seems better in almost every way. They are both good, but the Jag looks nice, plays well and with Rivals is a good investment because it is bound to get a lot of play. The Rivals expansion is quite addictive, similar to the Blitz addition I had back in the day.
My bearded dragon, Bubbs says it rocks!!!!
I hope that helps you.
