Should i go for UI5 or Functional

Hi Expert,

I am having 4.5 yr of exp in SAP CRM technical. now I want to move forward but get confuse where I have to go.

As market is growing rapidly crm I don't think so crm technology will sustain long time(pls correct if I am worng) so for future I think that crm functional will be good as I will involve in Business process(which is my interest).

Apparently I feel SAP UI5 I hot in market and booming. so I am thinking to join into my profile.

Please suggest. what will be the best for my future.

Ps note : I am huge interest in making carrier in gulf side .

Thanks

J
