Of the ones mentioned, I've used Firestone for an alignment and it went well. A local friend uses Firestone for most of his maintenance/repairs and has had good luck with them. From what he's said, their pricing has been reasonable and they haven't done too much upselling or BS.
I've also bought tires at Discount Tire, and their locations seem to be hit-or-miss (either super helpful and awesome, or scummy sales guy lying about inventory to get more $$$).
Stay the hell away from places like Jiffy Lube.
I mostly DIY (I only farm out things like tires, exhaust, and fuel line leaks).
