1) Altis spacious and fuel saving, good as a family sedan. Good
also if FC is important to you. Easy to sell on one hand few years
down the road as it's a good car with good market value. However,
too many Altis on the roads now may cause its value to drop as
there is too much of a surge in its numbers. Maintenance is also
fairly inexpensive. However, has image of family saloon, which you
might not get used to. And in terms of power, not much to speak of.
Just a very family-oriented sedan IMHO 
2) Not as nice as Altis but the other attributes aka fuel saving
remain somewhat the same. Still, I personally think it's a bit on
the ugly side 
Boot space is limited though. And let's
face it: for a few K more, I rather get the Altis but that's
personal
3) Sporty car, FC quite high, maintenance more expensive. Power
somewhat there. Market value is there but I think it's dropping
*shrug* Mitsubishi has concentrated too much on the Evo series and
neglected its lower end market, that is what I feel. Mitsubishi
engine have not really gone through any major overhaul/fine tuning
for some time? Not sure about this, you can check it out. But if
you are going for sporty look, get this 
Add a fierce looking spoiler and LED lights and you
will get many challengers on the roads 
My lousy 2 cents worth
P.S. I'm just giving a layman's view
