Seat selection for Mint is subjective to your preferences and number of travellers (and their travel preferences). Are there one or two of you? Do you like a aisle or window? Do you want to be next to each other or not? If you never get up on a red-eye you might like the window, if you're in the same row. The Mint Suite, overs a combination of window and aisle access. I prefer the Suite, as I can get in/out without having to step over anyone and also look out the window whenever I want. Suites, also offers more space to spreadout, the console near the window is almost always generating heat. So if it gets a bit cold, I can put the pillow on there to warm it up for a bit. Of course if there are two travellers, then you'd have to decide to sit together or take the suites.
