Actually it won't, sorry to say - at least for focal lengths under 20mm. I have both TV and GSO Plossls (the latter came with my dob and could not be opted out). Not sure about 5 times better, but a TV becomes "transparent" during observing whereas a GSO just won't. On top of the (expected) narrow Plossl FOV, it's got false colour, fuzzy off-axis stars, a fuzzy field stop and reminds me of my old battered Dick Smith 10x25 binoculars that I got 10 years ago, where cataract-like gunk is advancing towards the center of the eye lenses. The 15mm GSO now occasionally serves in my 35mm Lunt, where it works acceptably, just. The 9mm GSO, well I don't know what to do with it. I might just give it away. It's a true facepalm eyepiece. Fortunately, the dob itself is a whole different story in terms of optical performance.
That said, I agree that TV probably doesn't offer the best value (read quality) for money today. That one goes to the likes of ES, so excellent choice by Jim.
