I've had UPR, tri-ax, and MGW - also have driven on a pro-5.0 many times. MGW by far is the most refined, balanced, adjustable, and accurate shifter I've used in these cars. The UPR was more like a stock replacement that just wasn't quite as sloppy lol... Tri-ax is notchy and stiff, pro-5.0 is also notchy and has really short throws with a long reach.
MGW certainly does make the quietest shifter, though. The base is extra thick and really quiets down noisy 1st and 2nd gears.
