Is there any certain kind that'll be better than the others.
I'm going to depart from some of the posts which may be discouraging or possibly just plain wrong and go back to your question.
Krylon is good for your priming needs. Their Fusion primer + paint brand seems to work well. I have long used their spray red primer on ship models and build up the colors as on the prototype as laying over red lead. I also use the red primer as the finish on lower hulls, and have been known to use their gray on upperworks. Again, the tip is to go slow, better two or three light coats than one heavy one. You don't get as bad a heavy build up that may obscure details and/or craze the plastic. Krylon is available in most big box DIY stores: Lowes, Home Despot, Ace, etc.
Rustoleum Painter's Touch is also one of my go tos. They make different red & gray primer shades. Go slow! This is also available in many of the big box stores.
Testors spray paint is made by Rustoleum.
Walmart used to carry a spray brand that was recommended on some model boards. I shop Walmart only rarely, and not for home improvement supplies. If you have a walmart handy, try their paint on a test mule. Again, go slow.
I've used Duplicolor Auto primer on metal figures. It is a bit hotter and more of a heavy build spray. It has worked on my application. I got mine at O'Reilly's Auto Parts, but should be available in many auto shops.
Stay away from spray lacquers. They are very hot and WILL craze plastic. Even going slow, a second coat may craze the first. However, I have seen exquisite car models done in lacquer. It takes time and practice. Lacquer really needs to be sanded between coats to develop a deep gloss shine. I have done 15 coats of gloss black lacquer on a wood project, but it was flat surfaces and took time. If you must go this route, go slow and allow the coaty to fully cure before moving on
