As a 10 year veteran of all sorts of chinese HTs...
I have the BF-F9V2+, which is the same as the BF-F8, 3 power levels, and newer firmware. Hold "3" on power on to see the FW version, newer firmwares also have the voltage display if you hold down "0" while the radio is on. All of the newer UV/BF-series radios like these have better receivers, better sounding TX audio than the first generation models. the 3800mAh batteries aren't. I've had one apart to fix a broken wire, and I'm pretty sure I saw 2700mAh cells in it. Eh, they also make a "fat" short battery that's about 2800mAh (or whatever they say it is).
I also have had several of the UV-5R radios, and have noticed improvements over the years. I also have a UV-6R, which seems to work well, but, yes, also look at the UV-82 radios, they do have better TX audio, dual PTT, which allows you to transmit on either the top or bottom VFO, and they have special mics that have two PTTs, also. If you're using a single PTT mic, you need to turn off the dual PTT feature in the menu (or, might be in the programming software).
You can also look at the UV-5X3 tri-band. It's about $60, but is a 2m/220/440 radio. We've got more 220 repeaters in my area now, and several are linked, so we're seeing more traffic on them lately. It's 5W, has the newer firmware, and the quality seems the same as the dual band version. Comes with two antennas, one for 220, one for 2m/440.
I do have to admit, the Anytone HT I have AT-3208uv is a fantastic radio. Finally supported by Chirp, it has great TX audio, a good receiver, and the keypad functions are USEFUL. Ed at Importcommuncations.com has been working with anytone to develop their radios for the ham community, and they've been taking his suggestions seriously. Hopefully he'll be at Dayton this year.
Speaker mics are kinda sketchy, though. i'v'e had a few of them that sound good, some that sound hollow and muffled. i have found that most of them don't have the mic element up against the front of the mic, so there's a hollow space for sound to bounce around. replacing the element with a better quality one, and mounting it up against the front of the mic usually helps this.
