Verdict
The clearest difference is rating: SymPlayer at 5.0 against Slo Mo's 3.8. SymPlayer also leads on monetization model (free with in-app purchases vs subscription) and update cadence (every 10 days vs every 4 months). Slo Mo's advantage is ads (none vs shown) and ratings volume (2.9K vs 3). On price, in-app purchases and device support there is nothing between them.

Both are free to download. SymPlayer sells 3 in-app purchases, starting at $0.99 per month and Slo Mo sells 7 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.
