Both require AV. Both seem to have brighter cores. M86 might be a little more edge-on then M84.

Seems to be more head-on. AV required. Smaller than many of the others.

Very faint, hard to determine shape. A "speck" of a brighter core.

M60 is a bit larger and more visible than M59. It also appears to have a brighter core.
