When it comes to a "standard" tank, I do love my AeroTanks (V1 and V2). You can get the colored glass for them... Sweet-Vapes is where I bought my last smoke-colored glass for mine, and they had a rainbow available (at the time). The AeroTanks, KPT2, and KPT3 all use the same (size) glass section. I prefer the air-flow controller of the AT-V2 better than the V1, but both work very well, and both use the Kanger dual-coils (BDC) which are available in resistance from 0.8 Ohms up to 2.0 Ohms. The KPT2 (single-coil) can also use the Aerotank air-flow bases, so for $3-4 you can change your KPT2 or Davide tanks into Aerotanks, and still use the cheaper single coils. The Nautilus and Nautilus mini are good (although I'm not a huge fan, mostly due to the price and how fragile they are), and you get good flavor from them without going sub-ohm. BUT, the Nautilus, to my knowledge, does not have colorful glass available. The sub-tank mini and nano are available in colors (black, white, pink, and more are coming), and you can get coils for them up to 1.5 Ohm?? ( I can't remember off-hand, sorry). But, for me, the price, reliability, and function of the KPT2 (with air-flow controller) or the AeroTanks cannot be beat... when you're talking about a basic tank.
