The gum poses risk to the gingival tissues. It can cause gum recession. Not to mention it also taste terrible and hard to control delivery. Chewing it too fast can leave you woozy and nauseous.

The reason I prefer nicotine over other stimulants, it's oddly relaxing and motivating at the same time.

Caffeine either leaves me jittery or anxious or it doesn't work at all after 2 weeks. There is a ton of research out there proving the positive effects of nicotine.

I've never smoked, and tried nicotine gum to experiment with the cognitive effects. I managed two pieces of gum because of the taste and delivery control before I threw the rest in the trash... Haven't gotten around to trying a patch..

The patch stops working much faster while ecig's effect never seems to wear off.

I can only assume that it is because the patch maintains a constant level of nicotine in your bloodstream causing tolerance to develop faster and it is unable to spike the nicotine concentration unlike ecig when you can take a deep drag.

Ecig gives a totally different feeling than patch. You'll definitely feel it hit when you take a long deep drag.
