What's changed in 10 years? Prices of kits are about the same. The $220 US vendor I used in 2015, ebikeling, now prices it around around $400, but chinese competitors can still be found around $250. Same motors, but you might get a better display. A Bafang BBS02B mid drive kit which cost me $550 in 2016 is a little lower today, often as low as $450. There's other options for mid drive kits too like the ToSeven and Tongsheng and also the higher priced CYC. All three are torque sensing,
Might see UL-recognized batteries for kits this year. .I think Grin has them now with the pricing to match.
For the kind of bikes I ride these days, I like the torque sensing mid drive kits. I have two TSDZ2's, but they needed some electrical tweaking to fit my wife/me, and have a rep for high maintenance, I' hoping the ToSeven DM02 I bought can replace them and add some performance too,
