I'd say Norwood 2 in my opinion, with thickness slightly diminished overall. The answer to "best solution" is tricky, because all the treatments are a compromise.
Finasteride will lower your DHT and most likely maintain what you have with a chance of restoration, but has known side effects on libido
Minoxidil can revive hair at the application sites, but know with full certainty that minoxidil-revived hair will fall out if you stop the treatment, and it can cause puffy face/dark eye circles
Dermapens have documented results behind them, the only real downside here is the pain from using it and making sure you keep it clean, unlike minoxidil these new hair are pseudo permanent (still vulnerable to DHT, but not reliant on the dermapen after they grown in)
I would recommend IN MY OPINION definitely begin dermapenning (rollers rip too much) and consider finasteride (you never know for sure if you will get side effects unless you try it, but you can get a bloodtest that can reveal your current DHT/Test/Estro levels.)
If you do decide to take finasteride, maintain a positive mindset and try not to allow yourself to be psyched out. Anecdotally speaking, being anxious about side effects on finasteride seems to exacerbate their presence
