What "high-level result" you are talking about ?
There are three widely known methods for solving this puzzles:
1) For those with public keys available there is Kangaroo or BSGS
2) For the rest is just brute forcing (can be sequential, random or using those methods in certain ranges based on statistics/probability etc.)
In both of them the key is how much computing power you have.
That's all...
If you have 2200+ GPUs, you will be able to decrypt your wallet before anyone else within a certain time. Do you need something high-end?
The others you wrote, BSGS, kangaroo, vanity, bitcrack, keyhunt, many people already know all of them.
Conclusion = As you said, hardware power always means being ahead.
