am bit wierdo, love them both, and work around both too,
By all means, it is different worlds and philosophy, in maintenance and operations.
Be aware, TR on 139 cost bit more....
Almost all Mi17(1) are used and equipped in VFR config only, but de ice working well,
FIPS on AW139 performing yet?! Except that, AW 139 is serious IFR ship.
So in case you like to go off shore, go on 139
and if you like to eat sand and dust, go for Mi171...
Bus driver you will be on both except if you are "masochist"
to fly low level bad meteo night winter flights w/o radar in between
Adriatic islands, after that hilly Afgan can be nice vacation
