I have a few of most brands. Savvios- nice, can get spendy. Novos- need adaptors. Good pens, but the adaptor is a pain. V1-v2-v3- basic pens. Seem to work well, V1s are favored by more users. All Star- mine came apart mid pin. Stopped using it. A friend has an all star pro that did the same. The “bird pen” auto pen- I like these a lot. Gansulin autopens- love these too. Luxuras- my current favorite. Can be gotten domestically for $50-60 each; there are 2 vendors on Ali selling them for $30-40 right now. Then there are a few no name pens- one set of primary colored ones- functional, inexpensive. The “white plastic pen” sold on underground, they’re is a black and yellow pen sold by Molecular Mayhem- all solid choices.
