I did very well with Nikola and Quatumscape Spacs listings- Selling all not holding and sold well before Nikola imploded happily.
Reviewing the current crop at the same link you posted has me adding a few to my watch list. Some of them are fluff plus I think with the complication of a lot chasing the choice few or being left with the mediocre which are not likely to list at a stag event. Clearly a space to be aware of both the opportunities and risks. SV is possibly my pick Note- it seems heavily held via some large smart money which is happy to take profits now I see.
