Let’s Encrypt SSL certificate is not recommended for business level websites, as it is limited for domain validation only.
It’s depends on you. If you have a small website just go with domain validated SSL Certificate which start under $5.
If you have an eCommerce based website, then go with Organization Validation (available under $30) or EV SSL Certificate (available at $99).
I would recommend CheapSSLSecurity (https://cheapsslsecurity.com/) where you can get your choice SSL Certificate at lowest price with instant technical support.
https://cheapsslsecurity.com/ is the only place to get SSL Certificate at cheapest price starting at only $4.99/year.
If your blog URL is as "www.yourdomain.com/blog" then you only need domain validated SSL, but if your blog is as "blog.yourdomain.com" then you need to get a wildcard SSL Certificate.
There is no difference between Cheap and Expensive SSL, both gives same security & encryption.
Price of SSL certificate vary based on its type and encryption feature. EV SSL costs high as its gives highest encryption & strong validation.
> but if your blog is as "blog.yourdomain.com" then you need to get a wildcard SSL Certificate.
I don't think so. You can select any subdomain you want when you buy a certificate. Obviously if you get a cergificate for blog.yourdomain.com then it does not work on www.yourdomain.com.
If you only need these two subdomains, buying two separate certificates is cheaper than a wildcard one.
SSL Certificate selection depends on which type of validation you need for your website.
If you wish to secure your website with HTTPS only, you need a "Domain Validated" SSL Certificate
If you wish to secure your website with HTTPS & Organization name in URL, you need a "Organization Validated" SSL Certificate.
If you wish to secure your website with HTTPS by displaying Green address bar along with Organization name, you nee an "Extended Validation" SSL Certificate.
Additionally if you wish to secure multiple domains you need a SAN certificate and for security of multiple sub-domains you need a wildcard Certificate.
At http://www.cheapsslsecurity.com/ you will find DV, OV, EV, SAN and Wildcard SSL Certificate at cheapest price with heavy discount.

Both Comodo & GoDaddy EV SSL Certificate offering same security factors, but the price may vary because today Comodo became the leading SSL certificate brand that secure over 33% of website worldwide which is too large compared with GoDaddy.
Even customer trust level of Comodo is increasing day by day.
Why you are wishing to buy EV SSL Certificate directly form Comodo at high price, if there are many re-sellers available who offers at very low price?
CheapSSLSecurity is platinum re-seller of Comodo which offers Comodo EV SSL Certificate at very low price of just $113/year, which is too cheap compared with GoDadddy's EV SSL Certificate.
The price of Wildcard SSL certificate is a bit expensive because multiple sub-domains are secured with single certificate.
For a large business with multiple sub-domains (mail..com, blog..com, info..com, anything.com, etc...), if the business purchases individual SSL certificate for each sub-domain it need to spend more money, and the process will be so long as generation of new CSR, private key, certificate installation, etc...
A Wildcard SSL secures unlimited sub-domains which saves time and money as well.
$150 is much higher for a wildcard SSL certificate, Visit CheapSSLSecurity (https://www.cheapsslsecurity.com) where you can get Wildcard SSL certificate at $60/year for Domain Validation and $108/year for organization validation.
