Before I bought myself an FFB2 I talked to many of the top RoF pilots and my squadron mates and how much time you put into it and/or how quickly you can adjust should play a big part. At least in RoF due to their thin wing profiles many planes have very harsh and surprising stall characteristics so feeling the airflow via FFB is an advantage, especially if you do not fly 5 hours or more per week.
I only use 0.4 force setting, =FB=Vaal even uses only 0.35 so we basically have the hint of airflow but it is not really that strong, it just helps with flying those bastard planes like the Camel or Dolphin.
One problem with the FFB sticks is in sustained turns because you can easily get fooled into turning tighter and tigher because the stick forces will go lower and lower, you just have to keep an eye on the ASI. With a T16000M you will need muscle memory and a lot of experience/practice to fly sustained turns well though and scissors can become tricky.
Accuracy wise the FFB2 is pretty much the best but it shares that quality with a few other sticks like the T16000M, warthog, CH fighter stick etc. The Fighter stick has the advantage of the long throw, but at the same time it also makes you slower in quick manoeuvres.
Of course Clouds of Duty doesn't even support FFB properly so in that game (if you can get it to run without stuttering) a non-FFB stick is not really a loss so you will have to decide what game you primarily want the stick for.
Chosing between the Logitech and the T.16000M is a no-brainer though, definitely the T.16000M.
edit:
if you look at these:

J99*Sizzlorr: had a T.16000M, now uses a FFB2 and prefers it.
=FB=Vaal: as mentioned, FFB2
Josh Echo: T.16000M but has never tried Force Feedback in general
hq Peter Zvan: one of my squadron mates, he owns and has flown with a Logitech Attack stick, T.16000M, FFB2 and CH Fighter Stick and he prefers the T.16000M because he has the muscle memory and he flew with it before he got the FFB2 and the Fighter Stick
=FB=VikS: CH Fighter Stick
J2_vonHuetz: MS Prevision 2 iirc, basically an MS FFB2 without FFB but the same accurate potentiometers.
Mind you these are basically most of the best pilots in RoF and what they use might not be relevant to you. Most of my squadron mates who generally fly less than these guys have tried and since converted to using the FFB2. Some use the Logitech G940 because it has pedals and throttle but it is inferior in both accuracy and FFB afaik. Haven't tried one though.

You two should fly some duels, I can put the duel mission on the second server for you
