I have an extreme q and I have never heard of the underdog vape you speak of. But I can tell you I got my extreme q for 150$ off amazon, and it is an amazing vaporizer.. I personally highly recommend it.
Sorry for the late reply. I prefer the whip it is very convenient. And cleaning the the glass is very easy, they are small pieces that don't get very dirty. Anymore questions feel free to ask me.
To start off, both of the mentioned vaporizers are great products. I consider the EQ to be the best all around vaporizer and is good for someone new to vaping so they can get a feel for both the whip and bags. The heat up time on the EQ only takes a couple minutes, but it works best after being on for 10-15 minutes to get everything warmed up. Personally I don't care for the bag feature on the EQ or any other bag vapes. The bags never give thick enough vapor to satisfy me and with the EQ they can take a while to fill depending on the bag size. While you still have the whip option available on the EQ there are better options out there if you are not going to be using the bags. The UD is one of the best log vapes out there and is made to be plugged in all the time (otherwise the heat up time is roughly 30 minutes) so it will always be ready to go. It can conserve a lot more than the EQ while still giving big clouds of vapor when you want it to. It also works really well running it through glass. The EQ might be the better option if there are going to be groups of people using the vape, but if it is just 1-2 people then the UD will do just fine. Either one you pick you surely won't be disappointed as both of them are great products.
2 different vapes, depends on what you're looking for UD for efficiency, downside is longer heat up time so its expected to be plugged in 24/7 EQ for all around vape Look into the DBV/SSV as well, more comparable to the EQ as all around vapes DBV for example takes 3-4 minutes to heat up, sometimes less depending on outside temp

So ditto.
If you plan on using the vape in party situations, there is NOTHING that can beat bags being passed around (they're completely idiot proof) so if that is a consideration, get the Extreme. Otherwise, if it were me, and party situations was not a concern, I'd go with the UD being that there are no glass parts to break, no circuits or moving parts like fans or pumps to break and no where near the multiple parts that need to be maintained as there are on the Extreme. One other recommendation. If you plan on hitting your vape through glass most of the time, also consider the LSV. The DBV/SSV mentioned above are some of the hardest hitting vapes on the planet. ALL of these are great vapes. Get one to suit your intended usage.
