Guitar storage is something that I used to consider frankly too boring to really pay much attention to. That is until I damaged my first guitar and, like your first heartbreak, it stuck with me. If like me you have hurt your guitar before and want to avoid it happening again, or have a prized guitar (or many) and simply want to make sure it stays safe then you are in luck as there is some simple advice you can follow to ensure your axe is always in mint condition.

The best way to store your guitar does vary depending on your situation and priorities, for example if you play regularly you might want it very accessible, perhaps you play occasionally and just want it to be as safe as possible when not in use so protection is your best goal, maybe you have a guitar your really proud of and want it on display so aesthetics are super important. There is also the practical considerations of space as well, perhaps you have limited floor space but room on the walls or just need to store as many guitars in as small a space as possible.
If you want straight up the best protection while storing your guitar then the hardshell case wins hands down everytime. They provide a solid exterior with good interior padding while also providing insulation from humidity and temperature damage. After that for safe guitar storage I would say that a quality version of a guitar stand, hanger or rack also provide good solid protection. The lowest scorer on protection would be an Aframe guitar stand as they tend to be less stable and so the guitar will likely still fall if knocked but a quality tripod stand will give extra stability to protect from this. A gig bag will also supply some protection as many are padded but only from slight knocks and will still need to be stored properly.
For easy accessibility to your guitar then a stand, rack or hanger will all do the trick nicely. The only ones that limit this are hardshell cases or gig bags.
This is partly a personal thing but I would say that a guitar stand or hanger would be best. They display your guitar face out so you can see it in all its glory. Racks tend to store guitars on their side so aren't on show as much. In particular a wooden or quirky design can add well to the look of your pretty baby when youre not playing. Obviously cases and gig bags protect well but hide them from view and often don't look great.
If floor space is a premium then a guitar hanger or multiple guitar hangers can provide a good solution. Racks can also help store multiple guitars in a much smaller space than having multiple hangers or stands, albeit not as aesthetically.
