I will generally have to agree with Unsub on his point that the most useful knife is the one you can have with you the most often.
The reality for me is that an EDC knife in the day-to-day world is a folder for me.
But, some people might be able to carry a smaller fixed bladed knife as EDC.
However, in the field (hiking, camping, hunting, etc.), my first choices always seem to be around 4" - 4.5" fixed bladed knives. - Field EDC ... if you will.
I honestly contend that I could and WOULD use a 3.5" - 4.5" bladed knife about 20 times more often than anything 6" or larger. - even in the field.
The are quite a few mid-sized knives that are pretty versatile as well. I HIGHLY recommend the RMD and the HRLM!!! (I am also VERY fond of my Bog Dog and SS4 if you can find them and willing to pay REDICULOUS prices......)
The Chopweiler, Ratweiler and similar may not be as large as the Battle Rat, Rat Mastiff and such, but they are still quite large.
Opinions will differ. Some people are fine carrying a knife that weighs over a pound and feel they NEED to carry the big knife ... just in case.
I find myself to be plenty happy most of the time getting my knife tasks done with much lighter 4" or so knives.
I find chopping to be entertaining at times, but rarely needed for myself.
Others like to practice building "pretend" shelters .... just in case.
I love knives, but I would rather hike than chop.
I feel confident enough in having read some info, tips, etc. and in my own inginuity if a crisis arises. I can baton a 4" knife to function as a much larger knife if I have to.
No doubt most larger knife will still out-chop most smaller knife... but,.....
To each their own.
