Which manufacturer's Microcontroller do you prefer or trust for your " low power design applications "

I am currently designing with Texas Instruments microcontrollers and I trust them for low power applications specifically for those applications running on batteries. I think their ultra low power microcontrollers with Code composer studio which has in-built ULP advisory(not to mention GRACE too) is best for creating power controlled products. By this poll I want too know what you guys choose or prefer for low power designs? or Am I missing something already which I should have considered for power specific products? Please give your suggestions too.

Especially I found the software support to achieve low power consumption very good (this is e.g. in contrast with the Cypress PSoC chips where its more complicated)

Do you have a specific processor or model in mind?

The PSoC range from CYPRESS SEMICONDUCTOR is excellent if you want to use the analog peripherals they incorporate as well as low power capability.

According to this article (http://www.eetimes.com/author.asp?section_id=36&doc_id=1325355), this Ambiq Apollo M4F are more powerful and easy on the power than even a M0+ core. Thanks Doug.

Cypress' BLE controller is a system on a chip that includes an ARM Cortex M0.
If you want a really low power ARM Cortex M4, check out Ambiq Micro's Apollo.
Here are some cursory numbers for rough comparison:
TI MSP430 ~100 uA/MHz
SiLabs EFM32 ~ 150 uA/MHz (ARM Cortex M0)
Ambiq Apollo ~ 50 uA/MHz (ARM Cortex M4)
I expect the Apollo also has more capability than the other two, but you need to study datasheets to get a better idea of real power consumption for your application.

Actually, I am considering general purpose microcontrollers (not the bluetooth's one, as there are many other companies that are working on low power bluetooth controllers).
I have never tried cypress's controllers but I will.
