They work the same. LME uses a 1 piece billet aluminum design. Can't tell what the TSP guide is made of but it's not a 1 piece design, it has composite (plastic) pads on the guide ends. This makes it at least a 3 piece design. The pads will wear much faster than the billet aluminum. 60k miles, 120k miles, who knows. I'd be upset if the black portion wasn't at least steel though. It's definitely the budget piece between the two. I've lost $150 (way more) in a slot machine before, so the LME still felt like a good deal to me and that's what I'm running. I think the updated OEM tensioner would've been just fine, but I like billet stuff.
