How would you compare New IIMs primarily Raipur and Trichy to SIBM Pune?

I think you mean how the new IIMs can be compared to SIBM Pune. Rather than comparing, I will tell you what and why people are preferring the former over the latter.

Despite SIBM being an already well-established B School with better placement opportunities, many students prefer IIM Trichy over it. There are two major reasons for the same

1. IIM tag
2. IIM Trichy seems to be growing fairly well

The fact that people prefer it over SIBM, clearly speaks of its position in the future. Also, the IIM Tag seems very tempting considering its long-term benefits.

So go for SIBM Pune if you are only looking for a high-paying job. But for futuristic benefits, any new IIM will do.
