The altis has very good looks but there are 2 issues:
1. It's underpowered. It can never compete with other japanese cars, let alone contis.
2. It has reached the end of it's lifecyle.

If you're planning the get the Altis, I suggest you wait for the new model to be launched and hopefully Toyota puts in a better engine not recycle the same old 1.8 litre that was used in the current and previous generation. TBH I've not even seen one GR Corolla Altis on the road. I think no one is buying. The car looks very good but for that amount of money you're getting an old underpowered engine.

I believe the best way is to go and test drive and decide for yourself. From your description, the Toyota Corolla sedan is the better choice. if I'm not mistaken, the word "Altis" has been dropped is no longer used. It's now called "Corolla" only, or Corolla sedan if one doesn't want to mix it up with Corolla Cross SUV.

As usual the choice is dependent on priorities as there are pros and cons with both Civic and Corolla. I used to favour power and sporty handling but nowadays that's not so important anymore. For me it's a nice, quiet and comfortable drive which take precedence over everything else. Good NVH with minimal rattling sound inside the cabin. IN these areas, I generally find Honda vehicles from City to Accord to score poorly here. I test drove the Corolla GR Sport last year with the intention to buy one and the refinement in the drive and NVH are above average, in other words good. The downside of the Corolla, to me, is the lack of power due to the 1.8-litre engine and the high price exceeding RM150k. The power from the 1.8-litre engine is OK, and I probably could accept it if it's priced lower, but at RM150k+ I thought it's poor value. The hanlding and steering feel also were a bit lacking but that's irrelevant since it's a family orientated car, and moreover by benchmark was high comparing to my then Ford Focus 2.0 where the power and handling were one or two levels higher.

Sorry, I just read you owned the Accord and CRV and it's useful to note that your long-term experience coincide with my short term experiences having sat in my colleagues and friends Accord and Civic.

Coming back to point, for your criteria I think the Toyota Corolla is a much better choice than any of the Honda, provided you can put up with the slight lack of power and mediocre handling, and also the price. The price for the lower spec is RM140k up to RM148k for high spec and RM152k for the GR Sport version. To me it's a bit overpriced and poor value but that's just my opinion and also not forgetting it's not CKD but CBU from Thailand so that explains on the higher pricing. I owned the Nissan Sylphy 2.0 before and the NVH is among the best in its class or much pricier vehicles back in 2007. Back then I bought it for just slightly above RM110k I think. That's really great value but nowadays we can't get the same level of refinement and performance for the same money already. Sorry for being long-winded.
