I don't believe the F1A4 is better, timings would be different as its only made for detecting small metal parts, not gold, that's why they are on eBay with upgrades like timing settings and thresholds etc.
Sorry just my opinion, as it maybe a dedicated machine just not dedicated for gold.

No need to apologize for an opinion..
Didn't actually say the F1A4 was better, but owing both machines i can't safely say it is "comparable" pulse, reflect, if it hits a metal object it will energize it.. simple as that.
People love to overcomplicate things.. No detector on earth is a "GOLD DETECTOR"
the whites SPP is no different, nor is it any more effective... As for the F1A4, In comparison to my TDI SL, the TDI falls short, how? .. Oscilloscope tells me everything i need to know.
Less power per pulse.. means less depth, less chance to energize a deeper target..
Either way, I'll say your money is better spent on the Whites than the F1A4... Warranty is gold
