I like the Meguiars pads much better. Reason being is that the Burgundy pad just flat out performs like a champ. Cuts like heck yet still finishes down lsp ready + isn't hard the way most of the other foam cutting pads out there... Which means it doesn't suffer from the obligatory splater when you 1st start out. It's a little more dense than the polishing pad, but nowhere near hard.
The polishing pad does what it's meant to do and does it well.
Now as far as the LC Thinpros... Gray cutting pad: Its hard as heck. I've read some people talk about initially being hesitant on wanting to use it cuz it's so hard. [there's really nothing to fear, but it is somewhat stiff]
The Orange pad: They say this is also a cutting pad? Ok...
White Pad: Adequate polishing pad, nothing groundbreaking.
Red pad: see black pad.
Black pad: What the heck is the difference between the red and black? Why do they try to make me buy 2 different finishing pads? Not to mention 2 different cutting pads? That's what turns me off. Meguiars keeps it simple and does an amazing job.
I own a set of 3.5" LC Thinpros. But when it comes down to 5.5"-6.5" thin foam pads I choose the Megs without a doubt.
