B. arch or engineering? Pls help.

Hey! I've secured AIR - 375 IN AIEEE  B.ARCH. entrance...as lst year, SPA Delhi had taken even rank 459 in architecture after round 5, I'm pretty sure that i'll get through it. So hoping for an admission there. I'd always prepared for engg. entranes but did well in the arch. entrance :S

I'm getting average engg. colleges at my AIEEE rank - 24k. Shud I go for engg. or architecture?

I'm more passionate about architecture as i find it veryy much more interesting than engg. But I want  to have a secure future too...can't decide what to go for....pls tell.

If I get into SPA n work realy hard there, will I have a more secure carrier like that of a good engineer??
