LSE Finance vs WBS Financial Mathematics

I applied for an MSc Finance at LSE and WBS after doing my undergraduate in a stats-related course at Warwick.

I've received offers from both, but WBS has stated they "believe I am better suited to" MSc Financial Mathematics, and have hence made the offer for that course with a 50% scholarship.

I have interned in WM and Risk Mgmt at a MM firm, but hope to go into IB (LevFin).

Thoughts on which of these programs is better for achieving my goals?
