I have been vaping for 3 weeks on the same system as you 650mah ego with a CE4. Both knockoffs. They took me off the analogs and have kept me off so far. This is my opinion as a noob, and I dont intend to be insulting and I could be totally wrong. I think that its easy to become enchanted with this hobby since most of us literally owe our lives to vaping. nic is addictive, and the addiction turns into chasing the "perfect vape" Especially with the bombardment of information and reviews etc...on this forum. By the second week I had watched review after review on youtube of so much equipment and spent hours deciding what my next purchase would be. Should i go cartotank or vivi nova? top or bottom fed? I want ease of use and convenience and don't want to fiddle with rewicking etc.. What battery should I get, Vamo or Provari, or just settle for a twist for now? The whole time vaping my humble ego setup. A few days ago i went to my local B&M to ask for help in person. I went through the options with the employee, who was very helpful. He let me try a vape off a carto tank (not sure which one) with boba's bounty powered at a provari. It was great. I liked it. But then I realized that it wasnt THAT much more wonderful than my little ego setup (which I also had boba's in my CE4 at home). Instead of dropping the coin on the provari, I bought another ego battery as a backup, and a low res kanger T3. I like the vape from the T3, but I'm still satisfied with the Ce4 and can still vape it all day. I guess I am easily satisfied, I dont intend on vaping to become a serious permanent hobby that I wish to spend a lot of time and money on, its just something to keep me from smoking. at the end of the day its keeping me off analogs, nic is being delivered to my system, and I am happy. Like anything, there is hype surrounding these products and I pass most of the reviews off as hype. Is it better, sure, it probably is, there will always be something bigger and better. Is it worth it to me? no not really. I have decided to keep my ego/clearo setup and rotate juice that I like. That should do it for me.
