What would you say is the best or most reputable market to use for drugs?
In your opinion, who are the most reputable vendors for their respective drugs?
Would you recommend learning to use i2p for TMP rather than the tor browser?
Edit: thanks for the detailed responses :) If I narrowed down my vendor question to just lsd/dmt vendors, would that help at all?
I will try to explain you the situation.
You will find the addresses for the sites i mention in the sidebar here.
After the down of a lot of big DarkMarkets lately for various reasons, there was a bloom of a lot of different darkmarkets (refer to the side bar).
If by Reputable you mean big i guess you would like to go for :
If by reputable you mean the markets that have prooved themself to have active and efficient support that manage well their site, but are surely more little that the first 3 mentioned :
These are Darkmarkets, you have to understand that there is a lot of different Vendors on each DarkMarket, sometimes the market can be good or big but it doesn't mean that the Vendor is reliable or good or simply not a scammer.
Even the DarkMarkets very committed to search and ban the scammer Vendors have a hard times to detect them, so nothing can be ensured totally concerning that.
There are a lot, a lot of drugs or psychoactive substances, natural, chemical, legal, illegal, and i don't talk about the different quality in each drug...
Here is a good site about drugs where you will be able to see that it is almost an infinite subject so nobody will make some list like that.

Also because it is mainly subjective, do you think anyone will go and tests all the Vendors on all DarkMarkets? And how to be sure to cover all of them?
The right way would be first to be more precise on the "drugs" you are interested in, and after start to browse the darkmarket you will choose to look for that.
Eventually when you have spotted Vendors you are interested in you can search here for reviews or reports and make a post asking "can anyone vouch for this Vendor in this DarkMarket or have experience with this Vendor?".
You could also ask for the drug you are looking for and ask advices of the community on where you should look for that.
In your way to ask, it would be an Herculean work to do a list like that and it would be totally inaccurate anyway and probably highly subjective.
You will not always get answers or find something on the Vendor you want to test I have to say, but often the community will help.
Concerning TOR and I2P...
TOR is used as a standalone preconfigured browser that does not require an install and can be used on a separate storage like an USB, you simply put a onion address in the bar or a normal address if you want to surf a site anonymous (not always accepted).
About I2P it is a little bit more tricky to use but not complex, as it is a P2P architechture, there are a lot of guides on the Net and i think also on the SubReddit dedicated to TMP (Sidebar). For the moment the Network I2P seems to work well and support the growing number of users. Some people have put in doubt the reliability and Security of I2P Network but i don't think it has any technical base for the moment.
Note that I2P can be longer to set up (max 20 min i would say) and require more bandwith to be used. I have myself a very limited bandwith sometimes and I2P is not a good solution for me in that sense, but for anyone having an average decent connection for a fair price (Personal Dedicace to my ISP) it should be good.
Note also that TMP made the effort to propose also a TOR onion address so you can use TOR to browse TMP now if you want...:)
