I am looking to buy a new flat bar road bike for commuting and leisure cycles with my partner. I previously had a Decathlon Btwin aluminium drop bar bike with a Sora groupset (sold a year or so ago), which was a bargain, but the drop bars gave me back pain (not 100% sure if it was due to sizing or the riding position since it was my first drop bar bike).
I have an old flatbar hybrid junker that I've owned for 10 years which is super comfortable, and has never given me back pain. It recently reached the end of its life, and I'm looking for a nice replacement.
I have the choice between the Speeder 200 ($1100) and the Speeder 300 ($1330), and was keen to get opinions. Is the Tiagra groupset worth the extra $230?
Alternatively, would a step down to the Speeder 100 for $900 with the Acera groupset be noticeable for commuting/leisure cycling?

Thanks in advance!
Test rode both (if possible) and see which is more conformable. Group sets and components are easily replaceable later down the track, but that won't make a difference if you're hurting or uncomfortable on the bike as a whole.
