As others have noted, it's pretty frustrating trying to answer these kind of "yo, what's good" super vague questions. Extracting value from travel programs requires thought and thorough investigation and assessment of individual travel patterns.
For me, most of my travel is domestic and big-city, so a carefully considered combo of Southwest, Hyatt, and Delta for AK/HI/Non-WN airports works well for me. Someone who is looking to stay in small-town Idaho or fly to Namibia would get little to no value out of my points.
In other words, we have no idea without a lot more information.
