SPAC acquisitions raise significantly less money for the target acquired company, so generally a target only goes the SPAC route if their financials aren't in good enough shape to go the traditional IPO route (offering, dutch auction, or otherwise).

Most SPAC acquisitions involve high-risk companies, for recent examples: Lucid (10 years on and still no actual product for sale), Nikola (fraud), 23andMe (its financials are reportedly not in great shape), Opendoor (huge portfolio of risky real properties), EVgo (history of massive losses), Clover Health (accusations of fraud, under DOJ investigation).

SoFi is the only company I can think of that is going the SPAC route that was potentially in the shape to IPO (their potential IPO was tenatively valued at $17 billion at the start of 2020, but the SPAC acquired them for around 8.65 billion). They apparently chose not to IPO because they wanted "deal certainty." However, leaving that much money on the table is a huge red flag for a financial company; it suggests that 2020 was a bad year for them and that they wanted to avoid disclosure, or that their financials are not in great shape.
