I love when you can find workout ones and pull them off as leggings. They have to be the right material and not shiny but the workout ones tend to hold you in a little better all over and are generally more flattering than regular leggings I think.
I have had good luck with Ann Taylor, Hue, and the INC brand from Macy's - comes in a variety of sizes and is a nice ponte material and there is always some coupon. I prefer typically more of a ponte as it gives my legs a "leaner" line. Also typically not as see through.
I have the Matty M leggings, but can't compare them to anything else. They're cheap, but thick material and a wide waistband. The two things I don't like is that I get pilling between the thighs and the elastic sometimes twists although it's easy to correct.
Zella from Nordstrom, LulaRoe and if you really want to get $$$, I really love the Lilly Pulitzer Travel pants. I get them on sale or in B/S/T groups though. Full price is a bit steep for me, but they are very substantial.
