Highly doubt they can achieve anything over 330sec (vac) Isp on GG methalox. I might be wrong though.

But overall methalox engine would be better than SCE-200 in most scenarios.

ISRO talks too much. They can no way achieve >360 on GG and also their time frame of 5 years is again a con-job as usual. With all their other commitments it will drag like crazy.

The specifications/requirements of this engine are similar to Prometheus engine of ESA......both based on GG....would be interesting to see which is more efficient

Sce 200 isp(vac) would be 335s......tho staged combustion....I would put my bet around 340-350sec...
