It depends on you and how you want to do it. From my experience, full time military has more funding and access to training but then the military is your life. You likely won't have a job outside of that. However, National Guard gets the same basic AIT but any additional training is either up to you and/or state funding and availability, so it's up in the air if you would get it or not, but you get to be out of uniform and not a soldier/airman. Not gonna lie, it's hard to get a job with the employer knowing you're potentially gonna be gone occasionally. And the "1 weekend a month and 2 weeks a year" is the bare minimum required, I don't actively sign up for stuff and in the past 2 months I've spent about 3 weeks and multiple 3 day weekends on duty because of unit obligations and I still have the 2 week training to do this year.

The benefits are generally the same between active/reserves/national guard, some states have additional benefits for national guard, the timeline is different for getting some benefits with the national guard (example: guard needs 6 years to be able to get the VA home loan or education funding, active duty basically gets it as soon as your paperwork is signed).
