I am currently using a V5 and Nautilus and I cannot fault it. I started off with CE 4s and I clear 16s and was happy enough until I screwed on the Aspire. The difference is night and day. I have no experience with other tanks as I am relatively new to vaping, but the control over your desired vaping with the Nautilus is fantastic. It does look great too, in my opinion. If you can't live with the slight gap between tank and mod you can fit an OCD ring as was suggested to me by the members here. Sets it off nicely. Stack on the extra tube and a big battery, pop your crushed velvet smoking jacket and fez on and enjoy a great set up.
