Loving my sxt charger but eventually want to upgrade to a v8

Out of the trims what has the best bang for buck between the RT, scatpack, and SRT. Also what are some of the pros and cons in your opinion of each? It’ll be a while before I upgrade but I wanted to hear some input and not just the usual “why buy RT you shoulda bought a scat pack, why buy scatpack you shoulda just bought the SRT etc…”
