I have compared them both at work, though I only had the Inova T4.
The 7060 has a deeper reflector I believe and it throws a good beam farther than the T4. That said I believe the T4 has much better spill, with a cleaner transition from spill to hot spot. The Inova T4 is no slouch when it comes to distance though. I remember once I was searching a large beach park and the Inova T4 was lighting up areas pretty far away. Overally I like the T4 better. Better features, better size. I like the metal over the plastic but im sure they are both durable. My friend had a broken tail switch from a 4-5 foot fall. I think the light should have survived that better. They are both good light but I think the Inova overall is better. yeah i know, no tail switch and the throw is not quite as great, but I dont think the difference is significant.
