As Yokiamy said, opinions vary by person asked. 
If size of light matters & you want easier pocket carry, check out the Convoy C8 & M2; as well as models by Sofirn.
Sofirn has some great lights at reasonable prices too…… check them out. In fact they have a Group Buy going right now for the SP 32A V2.0
Check it out. Sofirn makes a great light!!
As far as tint goes, ask 10 different people & you’ll probably get 15 different answers. 
Check out the tint chart below. My personal favorites are 2A, 2D, 3A, & 3D… all of these are below the BBL on the chart you will notice. I personally find these tints to be the most NW (Neutral White), without the ugly yellow of WW (Warm White) or the harsh blue of CW (Cool White).
Personally, I also prefer the cooler side of neutral if there must be a choice.

The BLF GT & BLF GT70 are both great lights & fun lights too. But they are big & heavy. Really to big & heavy to be an EDC light, for me anyway.
As Yokiamy mentioned, M4DM4X & Neals Gadgets are both great places to get coupon codes for lights at great prices.
Good luck & welcome to BLF!!
