I agree that the $20 strike price is more favorable than $23, but the tenor is much worse than you suggest. The current warrants were supposed to be outstanding for 3-4 years post-merger, while the SPARs will expire the EARLIER of (i) 5 years and (ii) the initial business combination. Separately, I don't think the current warrants are a fair starting point--PSTH warrants traded 2-3x times more expensive than typical spac warrants (even after adjusting for PSTH's $20 NAV instead of $10 NAV) on the assumption that Bill would source a highly-hyped target. That didn't happen. The Remainco warrants and SPARs will reflect expectations/premium more in-line with the market. If you look at Softbank warrants for instance (which are more expensive than most), they are trading at about $1.50 (and lower-tier sponsors have warrants trading under 75 cents).
