Well, like they say, vape is progressive, in the beginning I didn't like box mods either, now, well have a few, and they put out 30-100 watts of power. About the size of a pack of smokes, so not really bulky, and no more incovienent than dragging a pack of smokes around, which most of us were more than willing to do.
Like them cause the stand upright and don't tip over easily. Can get some decent vape time out of later capacity batts, and can drive some serious vape power.
I love all things vape, box tube, 18650 & 26650 mechs, high amp regulated, box, tube, whatever, rba's tanked, drippers, tanked drippers.... it's all good. Main thing about portability is finding the right accessory. There are many side holsters and g cases that hold the mod and clip to you belt loop for both tube and box mods. Many jackets and vests have niffy inner pockets for storing cells, glasses and work well for vape gear too. Have a jacket that holds my scan proof wallet, my e-book, and my vaporizer. Can do the hands free pack and carry.
Start with what you like but never be surprised that what was not attractive today, may hold a gleam in you eye in a month or two.
One form factor is no better or worse than the other, and comes down to personal prefrance, or in my case, no prefrance besides it's got to kick some serious Vape Azzz.!!!! or something like that
