I usually stick to DOS 6.22 on 3.11 builds, though, for authenticity, but it is a bit easier to get ridiculous amounts of free conventional memory on 7.10 thanks to it supporting moving a bunch of stuff to UMBs (STACKS, FILES, etc.)
MS-DOS 6.22 can do the similar if not same. I never had anything less than 615-620 KB even with all the drivers and such (ZIP, SCSI, Stacker, etc.), and never faced with any application requiring more, even during the times. It's support for FAT32 might be considered as an advantage, but I never did any DOS rigs having more than 2GB partitions, anyway.
I suggest sticking with 6.22, myself. I like 7.1, its indispensable in a boot floppy for repair/recovery/maintenance purposes, but at the and, it's a hack from Windows 98 distributions, whereas 6.22 is a real standalone OS.
