The best for you depends on what your goal is and how much your budget is.

If you're a beginner who just want to have fun and not yet sure if you're planning on learning the hobby, get a cheap coaxial like a Blade mCX. It's so easy to fly (a 7-year-old girl can fly it) and tough enough to withstand ordinary crashes.

If you're a beginner who is serious to learn this hobby, skip the coaxials. The only thing you can learn from them is orientation. Orientation is something you can learn without having to spend money by getting a free flight simulator like FMS.

If you prefer learning to fly more than fixing after a crash (or you want to learn about fixing later), get an SRB Quark. But the SRB Quark is more expensive (initially) than other helis of the same type, though it is cheaper and easier to maintain. As a beginner myself, I learned to hover on the first day I got the Quark. Just don't forget, you eventually have to learn about fixing if you want to grow in this hobby.

If you're set to learn fixing and finetuning as much as flying, get any of the popular fixed-pitch (FP) helicopters. Many flyers recommend a HoneyBee FP. I would suggest to get whichever is carried by your local hobby store. It's surely nice to have easy access to spare parts.

I've learned a lot about fixing and finetuning when I got me a GAUI 200, which is collective pitch (CP) type. But I would not recommend a 200 class CP heli like the GAUI to those who haven't flown any single-rotor heli.
