If you are considering a Tesla, then don't watch the Phil Busardo video on it. It's a thumbs down.
The SVD is nice. I like the Sigelei V3/5 in a telescoping mod. Better quality and appearance, imho. GearQuest can be a bear. The truth is that other than quality and appearance, most of the sub $100 china mods use the same 33.3 chip, and other than a few changes in buttons and menu, are all relatively the same. Never owned a Tesla after Phil's review, but have many others. I prefer the Innokin and especially the Sigelei models in your price range. I think you can answer this question for yourself if you'll take the time to watch the many YouTube videos on these and perhaps a couple of other similar models. There's really less differences than one might think at first, and there are several poor quality ones that have issues that we hear about all the time, in your price range. It also helps to go to a local B&M and just hold them. I got an SVD, but it didn't take long before turning it sideways to read the display to annoy me. Hard to get that from the pictures. Also, the heft was always important to me. Goldy Locks zone, and all, since the thing rarely leaves my hand. I find the 134 too large, and the ego-t too small, but everything else is in between. Also, quality build and machining and to some extent, durability, can only be determined by holding them. The SVD rattles like crazy when extended BEFORE you put the battery in it. The Sigelei V3 never did for me. I guess I'm just saying quality and appearance have more to do with your selection than perhaps anything else, because performance is pretty close on all these APV's. Best APV's under $100 is the Sigelei V3/5 (quality and appearance), the Vamo (value) and the iTaste 3.0 (stick). Realize those weren't the choices or the answer to the question, but you did ask for our opinions. YMMV. My two cents.
