What is the difference between old-dos.ru & Winworldpc.com?

[Morea]

Both the sites offer a large list of old abandonware software and OS and betas, but what is the better? Are there other websites like those? Thanks!

I think both are BA mirrors or something.
One thing is sure though...Old-DOS.ru contains files from Winworldpc

[Overdoze]

They're both abandonware sites, like BA, but no contribution is required. Quality is questionable on both sites, and a lot of material there originates from BA or pre-BA times.

old-dos.ru is surely bigger than winworldpci, infact, for example, it has many OSs ISO files that winworldpci doesn't have, and then, it has even many ISO CD ROMs collection. However, all of this two are abandonware collection sites...

Both have the ISOs from BetaArchive, but you don't need to register to download. Old-dos has archives from WinWorld and WinWorld has the ISOs from BetaArchive.

WinWorldPC distributes betas of Windows (this I'm sure) up to 6.0.6xxx. Old-dos, I have seen like at least a year ago, is like separate beta website that occasionally contain something we don't have.

...is like separate beta website that occasionally contain something we don't have.

Old dos has no strict requirements that program must be a copy of original media, that's why apps there come from different sources: original media, backups, pirate disks etc. That's the first reason why they may have something that's missing here.

Secondly, it's non-english (to be exact it's russian-speaking community) and they put on their site many 'local' apps unknown to western beta community.

And at last (but not at least) they collect not only commercial, but shareware and freeware apps as well.
