Well, for one, when a new manual transmission lubricant is introduced into the 'box - it does not immediately "take"; it can take 500 miles to be fully-in-place, within the synchro's, and only at that time it fully reveals to the driver what the shift-feel is. That Honda lubricant, now, reveals its true character.
BUT: I provide a graphic, from Volkswagen, many years ago - commenting on the choice of a manual transmission lubricant. It talks about shift-feel, and that the quality of an oil to protect some of the elements inside of the box - in a superior way - does NOT correlate with the shift feel.
I don't know why ALL of the gears feel this way to you. Usually, it is the 1st to 2nd shift (other than shifting into first) - that feels stickiest. If this is the case, either start in first, and shift really slowly to second at hardly above a walking-pace... and this is 'real easy for the gearbox; do this for the first few shifts of the day. Or, if you park the car so there is a small down-gradient when you drive-off... start in 2nd gear... don't rev it up much at all ('real little, in fact, if you can manage it) for your start -- and let out the clutch really slowly... You will not add much additional wear to your clutch if you do this just the first few times of the day. Re the other gears, just shift-up slowly at lower rpm's... and similarly if you have to shift down while the 'box is cold... do so at 'real low speeds (lower than the normal downshift speed) - again for the first few shifts of the day.
I have long accepted that a manual box has to "nursed" to operating temp. In cold climate areas.... for daily drivers, I would never run a manual... in an extremely cold place. Other than that - I just accept this as a fact related to driving a manual... and I make adjustments in my driving, to suit.
I really do like manuals... but I 'kind of think, in my mind - that I am driving a Ferrari... (I say this 'cause when most Ferrari's were manual 5 speeds... the Ferrari clubs would counsel owners to either start in second, or start in first and then shift to third... until their gearboxes warmed up). So, I do this with my "Mazdarati" hehe.
