Nah just pick your favorite POS and try to articulate. I don't mind pictures either. Without any way to convince that you are doing something great, the chances that anyone will buy it with significant value are slim.
Well, here is one way to articulate it.
The only real driver of demand for a currency not backed by unique tangible properties (all cryptos fall under that category, PoW and PoS) is when something unique can be purchased for that currency and that currency only. That is the key to success. Why is USD in such great demand? Because you need it to buy oil, no modern economy can operate without oil. Create unique use cases that others don't have and you're ahead of others, but not for long if you stop creating those unique use cases. Algorithms, inflation rates, proof-of-xxx models are not significant. What really matters is what you can use it for. If you think of unique use cases for various cryptos, you may come to interesting conclusions. But you need to try to use various cryptos (PoW, PoS) to be able to appreciate their pros and cons and envisage their potential.
I won't pick one PoS, you know which PoS is ahead of others at this point. This can change, but the concept of PoS is here to stay as long as the concept of crypto currencies in general survives.
