Single strobe @60Hz (xl2411p) vs BFI Double @120Hz

I am mainly interested in Amiga emulation via winUAE but also MAME and vintage/FPGA consoles. All sourcers are of course 50/60Hz. I have read from chief blur buster that hardware solutions like the single strobe of the BenQ XL2411p is preferable due to less visual artifacts. But is this case if the discussion is limited to winUAE and perhaps MAME, where a 240Hz monitor could be used with BFI? Which would produce the better image?

120Hz BFI looks good on some panels, but very bad on other panels.
- Sometimes 120Hz BFI looks much better than native 60Hz strobing
- Sometimes 120Hz BFI looks much worse than native 60Hz strobing

I have some good news coming.... Keep tuned for a few days.

An announcement is coming of a panel that does a superb job on 120Hz BFI -> 60 Hz.

Thanks Chief

For the monitor I've been custom tuning:

Viewsonic XG270 with 'PureXP" MBR pre-tuned by Blur Busters!

Already tested with 60 Hz software BFI, using software BFI in order to convert 120 Hz hardware strobing to 60 Hz hardware strobing. It's a pretty good bright-colors low-persistence performer with MAME 60 Hz; does not generate checkerboard-pixel-patterns or reduced-color-depth problems like software BFI often does on TN LCDs.
