As the title says, which is better my rig will probably be heavy runninb method wheels and currie axles
 
Brushed motors tend to have better low speed resolution, better drag brake, and are typically cheaper to produce. They will function under water (at the cost of reduced lifespan).

But, they can be maintenance intensive if you want speed, and they will eventually wear out.

Brushless motors require very little maintenance, are capable of producing stupid speed and power, but many don't have very good low end control, and they tend to be more expensive. The sensored versions that are desirable for crawling don't like water.

All my Crawlers are running brushless sensored motors, brushless motors open a lot of options. Hope this helps and good luck on your decision, whichever route you chose you will be happy regardless. If you can afford to just spend the money once and get what you want, if taken care of it will last you a long time of fun.
 
For crawling, and heavier rigs (mine range from 6-9lb) i personally use 35t tekin brushed motors with either a brxl esc, or a ae2 with castle bec; i run both on 3s and couldnt be happier with performance. But it depends on what you want to do with your scx in terms of wheel speed to torque ratios vs price point. As Revoasian said they do require occasional polishing of the commutator and replacement brushes after loooong time or whenever required depending on how much you run it.

Personally I run a HH 35t Brxl wp combo on 3s, slow speed control is incredible. Wheel speed is good, enough to get my 9lb rig up most loose hills(The F650). My buddy has a similarly setup truck, only he is running a Traxxas venilon brush less system. Geared way down on 2s he has a touch more wheel speed, but not nearly the fine control. We take turns conquering tough obstacles, often it is the difference between brute power and finesse.
And just so we have a picture of trucks in the thread...

 
this is the first thing that crossed my mind when i first looked into crawling..
i only have one set up with brushless but the other 2 i have with stock brushed combo seem to crawl as good or better than the brushless setup...
i have way more speed with the brushless....
just wandering if i upgrade which way to go seems there's good options with either...
 
Brushed was the way I crawled, but now im full on brushless.
17.5 tekin redline and a mmp esc 14/90 works vary well on top and bottom.

This is the brushed versus brushless dialog from a few year ago, we have moved on from those times.

Quality 4 pole brushless motors like the Holmes Puller Pro or Tekin ROC412 have low speed resolution as good as any 3 slot brushed motor while providing greater power and wheelspeed at the same time. Holmes said a while back he was surprised at how many guys are swaping out brushed motors for Puller Pros in their comp rigs.

The only part of a sensored motor that needs to be waterproofed is the sensor board, which takes 2 minutes with some conformal coating (or you can have Holmes do this for you). Once waterproofed, a sensored brushless motor isn't really effected by being submerged in water or mud like a brushed motor (increased wear).

The cost factor is still applicable, brushed does have the advantage of being cheaper. If you have the budget for it, a good brushless system is the way to go.

I agree with your thoughts on this. I run HH 16T Crawlmaster and a ROC412 and both are awesome for crawling. The answer comes down to budget[emoji385]
