The blogosphere is already rife with "which version are you getting" and it seems Singapore will get both versions together, seeing that they lusted after our S4 Octa when they had the LTE version.

It depends whether you frequent or stay in an LTE enabled area. Many are of the opinion that getting an LTE model will "future proof" your device but the practical fact is that perhaps by the time you get LTE in your location, it would be the Snapdragon 2400 SoC with Adreno 690, or in the next 18 months you would have gotten a new unit with the newer beefier specs.

However if the delta between LTE and 3G is small, by all means the LTE model will be fine. Now all that remains is the answer to the question, which model will have more dev support.

Based on the s4 trends, I believe the snapdragon version would have more developed support.

And sammobile mentioned that if the country receive both lte and non lte version, Samsung will launch the lte version first. Hopefully we can get the lte version immediate upon launch and don't have to wait for another month like s4

Both version will have good developer support in my opinion.  But if u like aosp than for sure go lte.
