I have both and am planning to sell 1 before the Nintendo switch pro comes out.
Here are the pros of each of them
Trinket0 Switch can run more mods and supports injecting payloads
SX Mariko Switch has more battery life
For now, I'm thinking about getting rid of my mariko but if there's new development in the mod scene for mariko compatibility with atmosphere and injecting payloads, then the mariko would be the better console to keep for mods.
