Technic + addons with thought from a user's perspective
By that I mean that there are improvements here a user would normally think of when e.g. trying to cope with the fact that the original technic has no basic HV machines, such as furnaces. This mod adds those!
There are even digiline cables (they transport digiline signals and power), which would come into mind when trying to get info from a nuclear reactor, or anything in general without moving it (e.g. you may not wanna move a switching station from a good place to a luacontroller machine) Speaking of digilines, there are improvements in what machines can tell you; not only switching stations can provide lag it generates, but you can interact with even nuclear reactors, converters, quarries, etc., and I can tell about that because this has actual digilines documentation! I don't think the original technic has that. If you're not familiar with digilines, then I highly recommend you learn using them and the luacontroller, you can make anything with them using an easy language!
The mod also tells about its performance upgrades. I don't know how much faster this is than technic, but anybody would appreciate a speed boost.

why moreores?
if this is "meant as a drop-in replacement" i don't think moreores is a good idea, i don't have it in my world, if i replace technic with technic_plus_beta... mithril will only spawn in new chunks breaking consistency. and it is not a required dependency in technic_plus either.
