No the knacks feel really bad, take this easy example
Rogue climb related knack gives expertise on all athletics checks & a climb speed

Fighter climb related knack gives a climb speed, the option to spend exertion to reroll athletics when climbing,
and you ignore nonmagical difficult terrain.

druid climb related knack gives a climb speed and an expertise die on athletics checks specifically limited to climbing
(perhaps if you were using athletics rather than your climb speed to climb?) in comparison to the rogue's unrestrained athletics check expertise die, then it tops it all off with being "acclimated" to a situation likely to almost never come up in any game ever.

The others don't really feel like they hold a candle to their rogue/fighter counterpartsare generally feeling lacking. Compare te rogue's observer giving an expertise die on all perception checks & a +3 passive perception
View attachment 127571
to the druid's aerial surveyor also giving one expertise die to perception but limiting it to perception checks made from great heights or while flying without the passive perception bump making it worse in an extra way.

Eldritch survivor might actually be good depending on what the skills changes look like, but lets be honest & admit that some of that should be stuff nature should probably do by default from a druid given all the fluff & restrictions elsewhere trying to reinforce the fact that the druid is designed to interact with those things & stop the bad ones.

The expertise dice are a dramatic improvement over double proficiency, but unlike the rogue who has ability chains that can bump specific skill expertise dice the druid just has a chance at 3 to choose between a pair of potentially useful abilities or one of two others that give an expertise die on nature & animal handling respectively... Then their knacks include options that grant an expertise die on athletics checks
(athletics is not even on the druid skill list!) needed to swim(
lots of fish make those I bet?), an expertise die on athletics checks specifically to climb, an expertise die on whatever specifically when basically foraging for food. Part of the problem is that nature is generally a terrible skill & despite being a d8 medium armor divine caster like cleric who actually have archetypes to be a d8 heavy armor divine caster druid is still being punished for the sins of 3.5 CoDzilla* by actually being a d8 padded leather & hide divine caster & has everything under the sun (
needlessly?)restricted in any way possible to make sure it doesn't get delusions of the past. without some details on the new spell list stuff or weapon & armor stuff we don't eve know how awful this is or if all of these seemingly needless restrictions are even warranted.
. * CoDzilla was the 3.5 term to summarize
Cleric or Druid-(god)zilla,
