Some of us may have missed something. What rifle is this going on? Are we to assume it is just for use as a deer hunting rifle or does it have other uses?
All of the reticules you mentioned have advantages and disadvantages for certain uses. The normal Duplex is the simplest and cleanest. With practice, you can use it as a crude rangefinder if you know the dimensions on certain magnification levels. But the reticule is at it's best inside your cartridge/load's Point Blank Range, where holdover isn't necessary. It will be fast and accurate inside this range, without clutter or math.
The BDC reticules range in usefulness for high to not really at all. Done right, a BDC can get you on target fast to some pretty impressive distances. However, these almost always require the optic to be on a certain magnification level, usually at the upper end of the optic's magnification, and will require the optic to be calibrated with a certain load or trajectory. Within these limitations, a well designed BDC reticule rules the roost for most practical use, however, IMO. If you have a Trijicon ACOG-RCO on an AR-15, you might be surprised how fast and accurate you can be at some surprising ranges. That is one example of a BDC reticule done right. There is very little unnecessary clutter. Everything has a simple, intuitive purpose. You just put the stadia line that best matches the width of the target's shoulders on the target and fire. Your rangefinding and trajectory compensation is all accomplished at once and it can be very accurate. There is nothing better for a field rifle that is only going to see use with one primary round than a good BDC, IMO.
The various mil-dot and mil/MOA based hashed ranging systems also have their place. They offer the highest degree of precision and flexibility with range and load variations. You'll need to spend a decent amount of time in the field with it learning how to range with it, and dial in the proper "dope" for your load. Math will be required and it may take some practice before you're able to do this quickly and under pressure in the field (now imagine doing it while being shot at and you can understand why I think mil-dot is a poor choice for a SDM rifle). If you're going to be going back and forth between several loads or if you feel you actually need the increased precision at extended distances, it may be worth considering.
I have a Burris Ballistic Plex, and it causes more harm than good for all-around deer hunting use. It works well, at the range, but in the field, it's a distraction. My eye doesn't naturally go to the center of the reticle. I shot right over a deer at close range last Fall.
This would a more of an issue with lack of training or practice. Regardless of what you put on your rifle, you still need to spend enough time with it in the off season that you know how to use it in the field. This is true with any of the reticule options being considered by the OP, but definitely more true with the BDC and mil-dot reticules. It is true that BDC reticules can quickly become cluttered to those unaccustomed to them, but again, I saw very basically trained rifleman take a fixed 4x optic on a mass produced select-fire carbine shooting mass produced ball ammunition quickly and efficiently engage with precision pop-up targets from 200 to 600 yards. This is a level of precision not approachable by the standard Duplex reticule and a level of speed that the mil-dot systems can only dream of. But it takes training. You got to spend the time with it...
Same with the mil-dot systems, to an even bigger degree. It might be frustrating the first couple times you lay down behind a rifle and start trying to compute its range based on known dimensions and math formulas. I know it took a little while for me to get the hang of the NP-R2 reticule in the Nightforce my bro has on his AR-50. However, again, with practice it becomes faster and the level of precision you can achieve is much higher at extended ranges than the BDC. You're also not stuck with a certain load or trajectory. I will say that these reticules are best with higher magnification. A 1-4 style optic would be best with a good BDC IMO. To get the precision you want with the mil-dot reticules, I find it is nice, at least at extended distances, to have a decent amount of magnification. You don't have to have a space telescope on it. But the added detail provided by a upper end magnification between 8 and 10x, I think, would be worth it.
