It depends upon your needs, but the over simplified answer is: probably not. I'm not talking about the over all design philosophy behind such old software. It may be better for getting things done in terms of the interface and, as you mentioned, there's high portability. By portability, I assume you mean you can run it on anything that has an emulator for it. The trouble is how tied to the hardware it was. For example: 80 column mode was limited to particular video cards, and support didn't include the 80 column support found on later Apple II's. Have extra memory (such as an emulated 128 kB Apple IIe, so again were talking about very common hardware)? Well, you're stuck to the 64 kB (or less) of an Apple II or II+. Given that you have to restart the program to reclaim unused memory, this may be a bigger deal than anticipated. Such old software is finicky. Even Lotus 1-2-3 on a PC emulator would have its quirks, albeit not to the same extreme.
