I started off when Ego batteries and CE4's were the in thing. I did stop vaping for a while, but I still own the Ego and CE4 tanks ( I tried one the other day as my fiancee wants a vape, used a Protank mini on it, it was the least dense, smallest vapour I have ever seen).
I can't believe we got on with them at one point, and was actually successful in stopping smoking with them.
i am going to give my fiancee the Sig 30 on her birthday, with a nautlius, SMOK RSBT2, and an RDA, not sure what one to get her yet as she likes using my device (sig 30) for the flavours, and she has just stopped smoking and says it helps her not smoke, so as I am getting a small upgrade (sig 50) I might as well let her have this. (BTW I have bought her a nice present too, I am not just giving her used things incase people think I am being a cheapskate lol)
She can take small hits off an RTA, but she coughs if she takes bigger ones, so thats why I am giving her the nautilus to start with to get used to vaping. I let her use it when she uses my device ( we are together 24/7, so even if I did want to use the 30 I still could, just thought it might as well get some use instead of sitting in its box).
I find the 30 watts to be enough for me, well enough in fact. I am buying the 50 as if I run it at 30 watts that is not its maximum, and well, I like buying and collecting things lol.
So, I am happy with a sig30, soon to be 50 but I doubt I need them extra watts, its just nice to have them there, and vaping has evolved a lot since I last vaped with the Ego batteries and CE4 clearomizers that you had to replace instead of rebuild, rebuildables are new to me and I find them fascinating. Thats why I have a few RDA's and RTA's already, the lemo V2 is now my favourite 'take out' tank. It was the nautilus, but now I prefer direct to lung, and with the drip tip I use I would say flavour is around the same level, although the nautilus mini is an amazing tank for flavour.
Also, I plan in a few months to get the Sig 75 Temp control, I was going to buy it on payday, but I am going to wait a few months so I am not a guinea pig and any issues can be ironed out.
But, essentially, I am happy with a nice tank and something that can throw out 30 watts maximum.
( I usually only use about 12-14 of these watts in my RTA's and get the best flavour and reasonable vapour, I am using a 1.5Ohm coil in it though, as I wanted to make it close to the nautilus as that had amazing flavour, benefit of this is I don't need to run at super high watts and still get a nice tasting vape).
