Which is more reliable?
3.5L has been around longer but not sure if the MDS in the Hemi will be
problematic.

Both are good motors. Common problem with the 3.5L is cylinder mis-
fire fault codes (service bulletin out on this
problem) and water pump failure (even tho engine is free running I
have seen some bent valves when the belt breaks)
The common problem with the 5.7L is fault code P0404 EGR Valve
Failure. Note is important to use the good grade
motor oil in thses 5.7L engines because of the MDS. If you don't the
MDS will malfunction and turn on the check
engine lamp. Don't laugh I didn't believe it till I read the shop
manual.

Ummm - those two things (free running *AND* valves bent when belt broke)
are, by definition, mutually exclusive.

They're both Chrysler engines, they'll likely be highly reliable (well,
the 3.5 IS already proven very reliable). Think about it, which Chrysler
engines since 1930 have had ANY reliability problems? I can think of
two: the 2.7L v6 coking its own oil, and 2.0/2.4 4-cylinder head
gaskets. All the other new engines introduceed since the mid 90s- the
4.7L v8, 3.7L v6- have been flawless.

If you are considering a 300 versus a 300C Consumer reports says the 300C is
much less reliable. If it isn't the engine it has to be all of the extra
doodads.

My experience with the 3.5's has been great (I've had 4). For me, they get
better gas mileage than the EPA ratings. Certainly got enough power. The
only downside is the timing belt combined with an interference
piston-to-valve setup. If you think you might need the Hemi to compensate
for some sort of inadequacy, just remember that gas is over $3. It's higher
than it was after hurricane Katrina. $4 by this summer?

The appeal of the hemi isn't just the power.... it is much smoother and
quieter inside the 300C then the V6 3.5l 300.

Thanks guys for your opinions and advice.
Yes, Art that's what I have read in the reviews. It mentions that the 3.5L
isn't as refined.
