I think if I had only basic technologic knowledge I would go for the Monero approach, of course also other privacy coins work (e.g. Grin).
To my mind, it's not a good idea to use Grin because first of all, its CMC is 2.5 million (nothing) and daily trading volume is very low, a few thousand dollars. Also, compared to Monero, it's harder to exchange Grin.
P.S. I also think that when we talk about Privacy, not only transaction methods matter but we have to keep in mind the timing and volume of transaction. You can't send $8K worth Monero and immediately receive $8k worth Bitcoins. You have to make multiple transactions at different times to make it impossible to get tracked.
