I also bought the Smashbox TSV and have been trying out the Halo which I find gives a slightly heavier coverage than the BE and a stickier feel as it is applied so I prefer BE. I could see where I had applied Halo (yes, I was probably a bit heavy handed at first) but I'm now using them side by side, applying Halo over cheeks (not close to eyes) where I get a little redness to even out complexion, then use my BE over it and elsewhere.
I also like LG's Balance & Brighten and have actually used a combination of Halo, BE foundation, LG B&B and BE Mineral Veil on top, all without looking cakey! The secret is to go for light coverage of each product and layer up gradually.
