The main difference that i've noticed is the where the powerband is.
L98 - all the power is down low, pretty much now power over 4800rpm.
LT1 - more power at higher rpms, keeps pulling hard up to the redline which is about 5500-6000rpm.
Of course thats stock, with mods both can have different characteristics.

Generally speaking, LT1.
The L98 has some benefits over the LT1, but unless you're looking for some specific difference, the LT1 is definitely your best bet.

well i suppose it should be kind of cuddly,bit skinny,nice heads with perky little cam followers,obviously big mouth intake,some serious bottom end torque,a hell of a dwell and some serious overlap.

with that statement, the LT1 is a better engine in almost every sense of the word. 
State a good reason as to why you believe its better.....

on this forum that topic goes along with religion and politics in the category of "things that you will never win an argument over..."
both are sick motors, i think one should just pick the car based on miles, look, mods, etc. whatever you want, because i don't know anyone who's been disappointed with either.

Seriously, as time marches on so does technology. The LT1 should be better, but there is nothing wrong with the L98 either.
As others have asked, better at what?
This always turns into one of those "personal opinion" topics

Thanks for the reply's guys. I'm trying to learn more about these cars. I just recently sold my Grand National. Took me years to learn about that one.
I guess " better than what?"
Strength, durability. Which one will like a shot of NOS

The 84-85 L98 have forged pistons. The 87+ L98s and LT1s have aluminum heads. The LT1 reverse cooling gives it a higher detonation limit. The early motors might be better suited to NOS with the lower stock compression, but then again you'll need a 100 shot just to keep up with a stock LT4.

Can someone please post a side by side pic of the Torque and HP curves of both engines. I know the numbers but I've never seen the graphs next to each other. I like my LT1. LT1's can run N2O too. 
Thanks
Thanks
