I like cartos and I don't consider them sub par IMO, but then I don't know what you mean by "every regard".
I like IBTanked tanks. They are nice tanks and at a reasonable price. There are cheaper tanks but I have two of them and both have slippage issues where I've pulled the tank off the carto more than once. The IBTanked tanks have NEVER done this.
As far as cartos, lots like Ikenvape cartos. I really like their Platinum Punch V2 ones because I use dark, sweet juices and they seem to last the longest. Smok cartos are similar to Ikenvapes Fusion line. I'm not crazy about Boge cartos. For the juices I use they don't last long and I have to get past a weird taste when I first use them.
I don't. Cartos are sub par in every regard IMO, so I couldn't recommend that you get one of any kind.
