I basically liked the Pasela Tour Guards, but found they are too susceptible to side wall damage. I bought 4 at one point (2 700x25 and 2 27x1-1/8). I removed three from service long before the tread was worn out. Two were from abrasion to the side walls that left threads sticking out all over the place. I didn't feel comfortable running them after that. I was never even aware of doing anything that would have impacted the side walls. The third got a deep cut in the tread. It stayed stable for a while, and I rode it that way, but eventually it started widening and I retired it. Maybe whatever got that tire would have ruined any tire - who knows?

I also got several flats with the TGs, versus only one for the Marathons. On the plus side, the TGs are lighter, cheaper, and probably roll better. There was a gap in time between my use of the TGs versus the Marathons, so it's hard for me to compare them directly.
