I've never used a "Real" 74141, although I notice that mouser still stocks them for about $7 each. I've been using the standard $1/each plastic die K115D1 russian equivalents for my entire nixie clock 'career' and only had one problem. One of them stopped working after about a day of use.. I seem to recall that one of the cathodes stuck "on".. I replaced it and that was that. So, I have no basis for comparison to real 74141's, but I've had good luck with the russian ones. You can even get supposedly milspec ceramic die versions, but they don't fit nicely in sockets, so although I have some, I've never actually used them.
