I am using USBASP, I remember that I found it to be faster than USBtinyISP
Is there a newer/faster/better programmer I should consider when I need to order a new one now?
USBASP is plenty fast enough for me when I use it. What are you going to do with the few seconds that an alternative might save you if you can find one ?

I don't think it is allowed to post the answer to that in this forum. 
Seriously: it's mainly because the bitrate is very low, and a program+verify of even a small thing like a bootloader, takes relatively long time.
Really, I just wanted to know if there was a new and better toy I could get, one of my USBASP's died (enumerates on USB, but avrdude claims there is none) - so I was about to order another one to have in backup.
The Pololu AVR ISP programmer V2.1 is the best and most versatile I've ever used, and offers a separate USB-serial port as well.

I used Arduino as ISP on a separate Arduino board for most things.
The Pololu programmer has a good reputation.
Then there is the Microchip MPLab SNAP, which handles AVRs (included UPDI, PDI, TPI), PICs, and SAMD chips, and also supports debugging. ~$40m though.
