Hey pokemom! I have a mini PT2, which I like because it is glass. I use EVODs mostly, but I just ordered some Smok Aro tanks (which look a lot like the EVODs, but they are pyrex interiors, and less expensive than the PT2.) My EVODs really haven't been disposable (except for the shiny red one that cracked on the first day I used it

) I do swap the coils (pretty cheap - <$2 a coil) to extend their life. I think I fried one about 5 weeks ago (when I first started using the EVODs), and haven't lost one since.
I like my PT2 (although there's a tiny whistle - another thread tells how to correct that). Don't know anything about your other two that you've referenced.
Got some iClear 16 tanks with my first VV3 (not crazy about them - I keep frying the wicks and I'm not sure why). Also got the iClear 30 with my MVP. Haven't fried it (yet,) but it's that bigger tank size that like you, I'm not all wound up about.
I'm thinking my Smok tanks should be arriving via vapemail tomorrow. I'll try to remember to pop back here and let you know what I think of them. (Hoosierecig.com has them on sale, and I found the ECF coupon for 5% discount) If they turn out, they may become my go-to tanks.
Good luck!
