I think you have mistaken CPU Instruction Set and processor architecture
Both the processors are under same CPU instruction set,

According to "Marcus Fenix" Moto Defy+ comes with ARM Cortex A8 while SE has Cortex A9 which is better and energy...
Then go for Lava Xolo X900
It has intel's Medfield processor Atom z2460 clocked at 1.6 GHz which out-performs every dual core processor out there in India(except snapdragon s4 which has equivalent processing power to nVidia tegra 3 and not available in India)
It has good 8MP camera

Asus Transformer Prime costs 48k which is way too more expensive than his budget
I suggest
Samsung galaxy tab 7.7 - 28k
Sony tablet s -22k
or wait a while for quad-core tablets in your budget like
Asus transformer pad 300 - will cost around 30k
I guess price of Galaxy S II will drop within a week or two as Samsung is going to announce Galaxy S III today( 3 may)
so you should wait for few days and you can get galaxy s II for lower price.
OR you can buy Samsung galaxy nexus which has better hardware than S II and price is around...
You can go with Micromax Superfone A85.
It'll cost you around 15.3k
