Quite why TCS and Lions Air feel the urge to take on REGA is open to interpretation, but after TCS and REGA canceled their co-operation last year this was to be expected. There is currently no home base for the new operations' helicopter base, although Birrfeld and Dübendorf have been mooted.
I for one, would put my trust in
REGA; that organization has a stunning record and years of practical experience with many years of professional air rescues and medical repatriation flights.
