Electronics aren't really affected by cigarette smoke.
Unless a unit has been used as an ashtrays, smoke alone can't do any permanent or serious damage.
It will just get dirty faster.
Hours wise, 750 is really low and any dust should be limited to the external.
If you happen to notice any considerable dust buildup clogging its exhausts, then it might be useful to perform a more thorough cleanup, inside out. However, if you don't feel comfortable with it, leave that to a qualified technician.
Regarding which unit is best for you that depends on what you are after.
To me, the two units look identical, apart from the published contrast which is never a figure I personally take serious.
Furthermore, I've never owned a DILA unit so I have no opinion on them.
The only thing I could comment regarding using any of these two units, would be that they seem to be a bit low on brightness, for today's standards. Of course, you already own one and you are aware of the fact, so you might be absolutely fine with it.
But judging from my own needs, I'd try finding something with a published figure of 2000 uncalibrated lumens or above.
