Yes, really. The onboard avionics of the F-16 are more independent of ground direction, implying fewer support personnel and less infrastructure for command & control.
The -16 seems to have better weapons available for air-to-air (four AMRAAMs vs 2 Alamos for the -29 for medium range, 4 AIM-9s vs 6 Archers for short-range work), and is more capable in CAS, carrying a broad variety of PGMs.
It's also data-link compatible with NATO AWACs craft, which I'm not sure the Polish -29s are up-to-date on given that they haven't seen much recent use.
The supply of spare parts is also much more reliable, especially given current affairs, meaning that the F16s will probably spend more time actually flying.
So yeah, I'd gladly make that swap if I were in charge of the PAF.
