According to the definition of "strictly better" it's not even close. Journeyman is $5, Smithy is $4, which is huge. A strictly better card must have the same or smaller cost and do exactly what the original does plus something else, or must do precisely the same thing as the original but cost less.
From Magic: Lightning Bolt is strictly better than Shock because the only difference is that it does more damage, but everything else is the same, including the cost. Time Walk is strictly better than Time Warp because it does exactly the same thing with a smaller cost (Dang. You can cause your opponent to take an extra turn with Time Warp, so never mind. Not a strictly better relationship. Close, but not quite.) Lightning Bolt is not strictly better than Brimstone Volley, because even though it costs less for the same amount of damage, BV will sometimes do more damage, making it impossible to have a strictly better/worse relationship between the two.
The reason that I have to use Mtg Examples is because Donald isn't trying to crank out hundreds of cards a year and has been very careful not to make any kingdom cards that are strictly better than other cards, nor do overpowered cards cycle out of eligibility, requiring nerfed versions, so as a result there are no Dominion examples. As far as I can tell. I can hear the "challenge accepted" mutterings already...
