I see 420HC as well. Whether or not a Gerber will work for you comes down to your needs in my opinion.
If you will only use it occasionally and lightly, any sharp blade will work and a Gerber is just fine if you like the design and the price is good.
However, if you plan on hard use or using it often I would suggest Gerber is not really the quality you may need. If frequent use is in your plans I would suggest choosing a blade made from 154cm or better and buy it from a company that holds tight tolerances. I have not found Gerber to be that company. I would look to Spyderco or maybe Kershaw to find something at a similar price point (albeit a little higher) but of higher quality.
