Part of the reason I don't like parachute type sea anchors or drogues is the fact that all of your eggs are in a single basket so to speak. If the large parachute collapses or gets fouled, you're screwed. You have to adjust the lead length to get the parachute into the same part of the wave as the boat, but several waves away... and this may require you to adjust the bridle/lead several times in a storm. The Jordan Series Drogue is a fire-and-forget type safety device. Aside from checking on chafe, you don't have to adjust it for different storm conditons or wave size.
Also, the larger parachutes, which are not drogues but sea anchors, really put too much of a load strain on the boat, since the shock loads they can generate are likely to rip the hardware they're attached to the boat by out of the deck. A JSD is designed to not shock load the components on a boat, since as the loads are applied to a JSD, the cones react differently, depending on where they are in relation to the boat and the size of the load on the bridle. The higher the load, the more cones that become loaded and the greater the resistance the JSD provides... but it does so in stages... rather than all at once.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
